Purchased a Glock 23 last summer only because it was available for an incredible price. I really wanted a Glock 19. I have experienced the same wrist wrenching recoil that a previous poster has but expected it since I own other 40 S&W pistols and load my own ammo. So....? I ordered a retrofit 9MM barrel from Lone Wolf and now I have a Glock 19 and a 23. I think I need to order the 19 recoil spring though because the 9MM loads don't eject very well. They usually land on the bill of my cap :) The 9MM barrell is far more accurate than the 40 cal so I'm really happy about that. Anyway, in 40 S&W or 9MM its a great pistol and a great addition to my collection. And we can finally conceal carry in Wisconsin! Yippeeeee!

I posted my experience @ the range under the Glock 22 thread as I was discussing .40 issues but I gotta tell you, the gun shop/range where I bought my Glock 23 had a 10% off special going on in addition to their one month's free shooting (unlimited). It's a perk they offer when you purchase a gun from them. Great deal, huh? Plus the Glock 23 is really good. (It's a Glock, need more be said?)

After over a year of ownership, and over 500 rds fired through this pistol, I absolutely love this pistol. I purchased the Glock 23 after learning from my mistakes in purchasing the Taurus 24/7 (see my post in that comment section). I use the Glock 23 for home defense, and is my sidearm when deer hunting. It feels like an extension of my hand and with the night sights - I can shoot night or day. You grow used to the safety on the trigger, and doesn't give me problems anymore.

the best compact for more barrel

I have read these post reviews and others on Glocks, I am an old tanker from the the late 70 to the end of the gulf war and got out in then of 91. And have not had a gun in my had for over 18 years. I had give the thought of buying a hand gun for a while now. I have just bought the G23 the other week and went out to the desert and shot 300 rounds of the cheep wally world ammo ,that white box of ammo, and had only 1 miss fire, I do understand if you use crap ammo you would expect some issues, But all in all I was very impressed with the G23, The recoil was not as bad as what i was reading, the shot grouping was very good for me, all with in the kill zone, and most in a 6 inch radius, not shooting a weapon for over 18 years.

Hi, everybody: I've been reading this forum for a couple of years, and I joined tonight so I could post my 2 c on the Glock 23. I have bought and traded a number of semi-autos becuause they were not 100 percent reliable (1 Taurus9 mm, 2 Walthers, P22 and PPS 9 mm, 3 Beretta mouseguns). I about gave up on automatics. Then I read and heard about Glock, shot one and liked it. About 6 mos ago I bought a new generation 3 Glock 23. I have not modified it in any way (figured the Glock engineers know best). I shoot Wally World ammo. So far, have had it to an armorer once for light strikes (I was over-oiling it.) Returned it to the factory when it started misfeeding all brands of ammo. (About 500 rounds through it at that point)Glock replaced the recoil spring, the firing pin and the locking block pin , test fired it and stated "Meets factory specs". When I got it back, it immediately would not feed Federal Champion 180 gr flatnose. (5 misfeeds per mag). Called Glock and was told to shoot hotter ammo. They assured me it would go bang every time with hotter ammo. I also asked why the nose of the bullets seem to feed up the left side of the feed ramp (leaving a copper streak to the left of center) rather than up the center of the feedramp. I was told that underpowered ammo does not cycle the slide enough and the bullets do not feed straight as a result. Tonight, (about 250 rounds since the repair), I had what I thought was 3 jams with Remington UMC 180 gr hollowpoints. On closer inspection, I discovered the slide was locked back, with more rounds still in the mag. I shoot left-handed and I do not push on the slide release when I shoot. No visible problems with the follower or mag, and the spring on the slide lock still holds it down. My choice is to trade it, or to send it back to Glock and then trade it, because no matter how they fix it now, I do not trust it. If this is the best, most reliable semi-auto ever made, I will probably join John Dillinger and stick with revolvers. I bought this pistol to shoot. In the short time I have owned it, I have spent over a hundred dollars in extra ammo (extra shots to see when it is going to malfunction), plus 60 dollars for shipping to Smyrna GA. I bought this pistol partly on the reputation that it would shoot anything I fed it. The techs at Glock now are telling me that a pistol that will shoot all ammo is a fairy tale, and I should use premium ammo. I always try to learn everything I can about how a gun operates. But every semi-auto I have ever owned, I have to be a gunsmith to get it to work part of the time. I think that should be Glock's job, not mine, in maintaining the Glock Perfection image. I really hoped that this would be a reliable pistol. I wanted to like it. I don't think I will ever completely trust it when I need it. This Glock is just another temperamental semi-auto. What I have learned is, the bigger the hype, the greater the disappointment. I wanted to like this gun, but I give it one bullet. Thanks for listening. And thanks for a great forum.

I just bought this gun tuesday.....took to range last nite,,,,it shot very well....

Taylor W. from Blue Point, NY on Mon, 4 May 2015

I had one of these and won't rate it as I only had it for a while before I sold it. I did get pretty good with it toward the end, for a small gun it was relatively accurate. I found the grip to be almost impossible to get my hand over big hands, and the front part was smooth and equally useless. the recoil was way more than it should be due to the light weight, in fact the gun functions worse and worse as you empty the magazine. my buddy who is small/average says recoil is high as well, I have shot the Xd it is much better for big hands. I also handles recoil much better I had a .45. The new ones should come with adjustable grips so problem may be fixed.

JustBen...I too am fat. What I bought for my Kimber Ultra CDP II was a Fist model #K7 kydex IWB (with split J-hooks). It's highly changeable on kant and I use it at 11 O'Clock (cross draw) while driving (or other prolonged sitting) and at 3 O'Clock while standing or walking about. It has no retaining strap but is so closely form fitted to the gun that it captures it well (won't fall out when upside-down). It retains shape and stays open thus re-holstering is a sure, simple movement. It's available for Glocks also, but is a little steep in price (about $60 plus any options offered). It's the best holster that I have and I do plan to get one for my Glock also (as soon as I can convince myself to part with another $60)! It's excellent, well made, glass smooth on the interior and flat & wrinkled on the exterior...I believe that black is the only color offered. Comes in two material thicknesses...thin & ultra thin...I can't remember which one mine is. Check them out here:

Incredible Portable Undeniable Reliable Defense. Glock 23 I rate it life time achievement award type stuff. Point aim and shoot with this should allow for you to concentrate on other bad guys because they do like to hang out and drink and smoke together. They really hope you dont have a Glock 23. First time I shot a gold dot into a Muddy clay creek bank and I blew a hole the size of a watermelon two feet deep I realized .40 caliber is something special glock on

Jerry R. from Philadelphia, PA on Sat, 6 Sep 2014

Anyone have any experience with cutting a half round slot on either side of the bottom of their Glock grip. This supposedly allows you to grab the magazine and pull it out in the event it sticks during a reload. I can no longer grab my magazine from the back since I put one of those plastic plugs in the hole just behind the magazine, and thought this might not be a bad modification. has a video on several modifications including this one. Go to media and find the video about pistol modifications. Thanks for any comments.

Jerry R. from Philadelphia, PA on Wed, 27 Aug 2014

g41: Thanks for the expert info. I will try the pencil trick. As someone who does not want to screw up or have a malfunction, I really appreciate this forum and the help. Thanks Ben PS: I have the Tritium sights, a stainless guide rod, the 3.5 pound trigger connector, and absolutely love that gun. Best one I have bought so far.

Bryan N. from Stevenson Ranch, CA on Tue, 26 Aug 2014

What can you really say .... it isn't pretty, it isn't glamorous or feature rich but it does it's job and it does it very well ... It goes bang when you pull the trigger and it hits what it's aimed at ... every time.

Eric D. from Cambria Heights, NY on Mon, 25 Aug 2014

Plenty of video disc available on the full cleaning of our Glock. At least once a year, take her down and go over it. We Glock owners have the very great privaledge of not havng a lot of parts to chase around the room. ( less itsy bitsy parts to contend with than most) Aye well I have to get out of here because I have been known to have an opinion! :-)

Jerry R. from Philadelphia, PA on Thu, 21 Aug 2014

djk3381: Just picked up Gun World magazine for March 2010. They have an article with 6 modifications for Glocks. One of them is the guide rod and spring. Check it out.

Willard O. from Danville, CA on Wed, 5 Feb 2014

Whalzi, I can't recommend using reloads in a full automatic mode pistol. I don't even like to see people doing 'double taps' with them in a 1911. All you need is the 1 in 10,000 squib load to be in that clip when you go full auto or double can't react fast enough after hearing the unnatural pop rather than the normal bang and that could result in an exploding gun (obstructed bore followed by a good round being fired in it) assuming that the action continues to operate with a full cycle. Secondly, I would be pressed to be able to maintain any safe directional control of a compact pistol during full auto mode of fire...but, maybe that's just me. Also, there may be trade-offs in rapid parts wear and of course dwindling ammo (and cash) supply.

Willard O. from Danville, CA on Fri, 6 Sep 2013

Navydoc, give us more specific info: brand & country of manufacture of ammo, weight of bullet. Also, are you shooting clean ammo (no dust, dirt, grease, oil, etc on the outside)? Are you shooting a gun that has a clean, dry (no oil, etc) chamber and bore? If everything above is clean & dry then I suspect poor ammo (high pressure 'hot' load or improperly annealed brass cases) as a starter. Since the failure is on two different G23's, I doubt if you could have a failing part there...unless damaged by hot ammo, etc. I once had some Chinese ammo in 9mm that was very hot. Also, some 9mm MAK Russian Makarov ammo is loaded to the extreme. Be careful what you feed your Glock (or any gun for that matter) and be certain to dry all ammo and gun parts (that contact the cartridge or bullet) including the magazine lips and follower, to be free of oil, lube, lint, dust, etc before loading up and shooting. What do the case rims look like on the fired cartridge? Badly bent, nicked, or torn brass? Have you and your friend modified the extractors or any springs on your pistols (as far as you know)? Anybody else got some help for our friend here?

Agustin J. from Lowell, MI on Mon, 25 Feb 2013

wonderful weapon right out of the box.

Clint Q. from Omaha, NE on Mon, 14 Jan 2013

240sx, take a plunge on the G23. You won't be disappointed. If you are looking at a .45, be ready to shell out loads of $$$ and accessories for a quality one. All in all, I don't believe there is a huge different between a .45 and a .40. That's just my humble opinion. I can take down a man with the .40 or a .45. Use the right load/handgun for you and it should get the job done if a situation ever comes up. Three guns I currently have: G23 (favorite in the car) P2K .40 V3 (full-time CC and always with me) P228 (old timer that will always get the job done, had it 12yrs) My personal favorite loads: Remington Saber Bonded 165gr for my G23/P2K Federal 9mm Luger (+p+) 115gr 9BPLE I leave the .45 to the ppl that likes everything big. :) Size is important no doubt, but put it where it counts time after time again will also take care of business. That comes with practice, practice, and practice.

Glock 23 Questions & Comments



Jerry R. from Philadelphia, PA on Wed, 13 Jul 2016

I can just see myself at WalMart hanging around the Douche aisle. It was bad enough the 20 minutes I spent trying to find the right color bright orange nail polish to paint my sights with. But I guess I would fit right in at WalMart now that I think about it.

Chester D. from Burket, IN on Wed, 13 Jul 2016

Doesn't everyone use Summer's Eve on their pistols? Works better than bore solvent!

Jacob S. from Indianola, MS on Tue, 12 Jul 2016

Justben, I was just looking up the G19 recoil spring and it turns out the G19 and G23 are one in the same. Looks like I'll have to work on my recipe for loading 9MM and make them a bit hotter for this gun. It shoots 9's just fine but they don't eject very far, generally landing at my feet.

Jerry R. from Philadelphia, PA on Mon, 11 Jul 2016

Excellent. I got my current guide rod and spring online at the glockstore. Sounds like a little time on the internet and I will be all set. Thanks Bro. JB

Jacob S. from Indianola, MS on Mon, 11 Jul 2016

Thanks justben, Regarding the Lone Wolf retro barrell... But first, I hope no one got the idea that I was offended. I don't get offended. I own a small retail business. If I got offended easily I'd be pissed off all the time :-) ha!ha! I've been around this site long enough to know when to brush off someone's foolish remarks. That being said, if you order the Lone Wolf 9MM barrel, part #LWD-239N you might want to order the Glock 19 recoil spring with it. The 40 cal spring seems a little too stiff for 9MM. I don't have the part number for the spring since I haven't ordered it yet. You will also need to order a few 9MM magazines, part #KCI-G1915. At $12.50 each they are cheap and work well.

Jerry R. from Philadelphia, PA on Mon, 11 Jul 2016

@Jetsburg: One indicator of folks around here is the number of posts they have made. Take a look at their number and if it is really low, don't take any criticism to personally. We all say thing we wish we had not while in rookie status. Glad you shared the barrel idea. I have been wanting to do that for some time, and I think your experience has convinced me to go ahead. Thanks ! JB

Jacob S. from Indianola, MS on Mon, 11 Jul 2016

Wow! It's interesting how when someone finds a cool retrofit to his pistol some of you "experts" jump down their throat. Now I'm sure you're all some kind of mercenary dudes who kill for a living but I'm just a small town guy who likes to shoot a lot and share my experiences with other interested parties. This site has always been a fun sight to share information and not be criticized by those who imagine themselves to be para-military hard asses. Lighten up and enjoy the conversation and don't be critical. You all are entitled to your opinion.

Jerry R. from Philadelphia, PA on Sun, 10 Jul 2016

In stressful situations I tend to heel the G23 and shoot high right. I believe it is the extra recoil that works against my personal ability to be accurate. For whatever reason I shoot the 9mm with a little less recoil anticipation and more confidence. If I want to shoot the G23 accurately I can do so target shooting and taking my time, but if I want speed and accuracy under stress I prefer the 9mm. Just my own personal experience. I do not disagree with anything you have said.

Chester D. from Burket, IN on Sun, 10 Jul 2016

I disagree with your statement that a 9mm is more accurate than a .40 S&W. I shoot a Glock 35 on a league and I shoot it as accurately as I do a .45 ACP and 9mm. The bullet is going to fly straight down the axis of the bore with acceptable ammunition. I would agree with a statement that second shot placement time of a .40 is longer due to the increased recoil. I also do not like to train with a different caliber that what I'm going to fight my way out of a jam with.

Jerry R. from Philadelphia, PA on Sun, 10 Jul 2016

Don't get me wrong, the G23 is a great pistol and I own one for the same reasons you do. But, the 9mm is more accurate and shot placement does trump caliber. It sure sounds like a good idea to at least have the 9mm conversion barrel for practice and those long training weekends.

Chester D. from Burket, IN on Sun, 10 Jul 2016

I can't think of a reason as to why I would shoot 2,000 rounds in three days let alone one handed. I carry a .40 for the increased muzzle energy, stopping power and wound channel it carves in comparison to the 9mm. I have shot 600 rounds of .40 in two days more than once for training but this was done in conjunction with firing 3,000 rounds of 5.56 X 45mm. If you find the .40 that bad, I would order a bottle of Summers Eve to go with that 9mm barrel.

Jerry R. from Philadelphia, PA on Sun, 10 Jul 2016

Shoot 2,000 rounds in three days all one handed and you will be online ordering that 9mm barrel as quick as you can say mastercard.

Chester D. from Burket, IN on Sun, 10 Jul 2016

I don't understand this "wrist wrenching" recoil others are referring to. The most brash of all of the Glock .40 cal models has to be the 27 and I don't find it to be "wrist wrenching". A bit brash, yes but wrist wrenching, no.

Russell C. from Chambersburg, PA on Fri, 6 May 2016

Sent away for guide rod & spring assembly from Lone Wolf for my G23 last night. Now I'm thinking possibly a barrel from them as well. This gun is going to be my "baby". As much as I love all my guns, this one really speaks to me. At the rate I'm spending money on guns themselves, I won't be able to buy any ammo soon, lol!

Jerry J. from New Smyrna Beach, FL on Thu, 17 Dec 2015

The only thing I dislike about Glock is its safety features

Jerry R. from Philadelphia, PA on Fri, 2 Oct 2015

I had my G23 out today drawing and shooting on the move. Getting ready for the Buckeye Firearms Fun Shoot next Sunday down at Tactical Defense Institute in Southern Ohio. I only shot about 50 rounds and got one jam. It was due to limp wristing. My gun will jam if I am not shooting right. Practicing with my Walther P22 and not enough with my primary carry weapon is the culprit. I need to be more religous about practicing a couple times a month with it.

Benito T. from El Paso, TX on Fri, 2 Oct 2015

Thanks, Ben, Yeah, a friend of mine said I had a collector's item: a G23 that jams. The Gen 4 G22 is still working fine. My wife shot it and she noticed the low recoil compared to a 38 snubbie. Further update: Now have about 400 rounds thru the G22 with no malfunctions. The only problem I've had, I was expecting. The pistol I have is an early Gen 4, without the counterbored slide, and the recoil spring assembly is already looking like it will come apart. I had read about those springs on line, and I called Glock. They are sending an updated spring assembly, which has a reinforcing washer or bushing between the larger spring and the plastic guide rod end. The bushing helps keep the spring centered in the slide end, and reduces wear, and spring failure. Fred, the tech I spoke with at Glock, admitted re the G23 that "sometimes you get an individual pistol that is finicky, and it will drive you crazy". In my opinion, the main reason the G23 jammed was that bullets tended to feed toward the left of center of the feed ramp, in spite of "meeting factory specs." I'm currently waiting for Wal-mart to restock the Remington UMC .40 in 180 grain HP. That was one of the bullets that jammed the G23. I expect it will feed fine in the new pistol, because bullets feed centered in the new pistol. And so far, it has shot everything I have fed it, including Tulammo. Again thanks for the feedback and encouragement.

Jerry R. from Philadelphia, PA on Thu, 1 Oct 2015

Beachcomber: Glad to hear you like the Gen4. Would'nt mind having one myself. I have been in manufacturing for 34 years now, and I can tell you that it is not always repeatable. Even the best manufacturing processes and companies have variation. On critical features, the good companies identify them and track their "process capability" to ensure the parts are held well within the tolerance. Most companies shoot for a Cpk of 1.33 on criticals. But even if you acheive a 2.0, statistically you can still expect 3.4 defects per million parts. I know Glock makes millions of guns, but the statistics are there, and "shit happens" (that's the technical term for a defect - LOL). Still one of the best companies and guns on the market though, Happy Shooting now that you are not part of the 3.4 parts out of a million. Ben

Benito T. from El Paso, TX on Tue, 15 Sep 2015

Thanks, Justben and Steelilfe, for taking my posts seriously. (This is Beachbumm. I am now registered as Beachcomber). I did not give up on Glock. Update: In spite of what the techs told me about underpowered ammo feeding to the left of center of the feed ramp and jamming, I decided that the G23 I had was in fact a lemon, and was jamming because of ammo not aligned properly with the feed ramp. I suspect there was too much play in the mag lock, allowing the mag to twist out of position. Just my guess, but it was not reliable. Then, I had slide lock problems on top of that. I traded the gen 3 G23 on a gen 4 Glock 22, and I'm not looking back! 300 rounds so far, cheap and expensive ammo, it all works fine, like I expected any Glock to do. I give the Glock 22 5 bullets. The interchangeable backstraps are a plus, the double recoil spring actually does reduce recoil. I will not be buying another G 23. And the amount I "lost" in trade will quickly be made up for not having to shoot the hotter ammunition recommended for the picky G 23 I had.

Scott C. from Boaz, AL on Mon, 14 Sep 2015

Beachbum you have had some good iron to have that many problems I feel bad for you!!!
