Yoakam Posted January 2, 2019 Share Posted January 2, 2019 Last year I purchased a brand new G34 Gen 4 and am just now really getting time to work with it. So far I have changed the sights to TTI target sights, guide rod and 13 lb recoil spring. The sights have been centered with my calipers...but the gun consistently shoots left. I found the locking block pins to be very easy to remove...in fact one of the pins nearly walked completely out during a firing string. I was able to replace the locking block that I had from another Glock that is extremely tight fitting. Anyhow...the gun doesn't group as tightly as I would expect. I haven't noticed this issue with any of my other 7 Glocks. So far I have tried different loads...back straps...factory springs. I realize I can drift the sight...but I'm OCD when it comes to them being aligned. Has anybody else had this issue? Any suggestions? Also this is all slow fire standing from about 10 yards.

dapribek Posted January 2, 2019 Share Posted January 2, 2019 Is it possible to have someone else fire the gun , just to insure that you’re not the cause of it shooting left? Link to comment Share on other sites More sharing options...
Yoakam Posted January 2, 2019 Author Share Posted January 2, 2019 Yeah. That's my next step. I need to find someone that mostly shoots Glocks though. I'll probably take it to the next local match and let a few guys try it and see. It's certainly been disappointing. I have been expecting this to be a tack driver...and so far it hasn't really impressed me at all. Link to comment Share on other sites More sharing options...
rooster Posted January 2, 2019 Share Posted January 2, 2019 Get a new locking block pins should not walk out. If that doesn’t fix peen the ends of the pins. Shooting left is common among right handed shooters. Some people say practice pulling trigger straight back, or just move rear sight a little right. You can buy anti walk pins.

Yoakam Posted January 2, 2019 Author Share Posted January 2, 2019 Thanks for the suggestions. Has anybody tried the SS locking block from Lone Wolf? Are they GTG? Link to comment Share on other sites More sharing options...
rooster Posted January 2, 2019 Share Posted January 2, 2019 I did try the locking block from LW, sent it back, it was worse than stock. Don’t know if it was just a fluke, but didn’t want to hassle with it. Link to comment Share on other sites More sharing options...
Yoakam Posted January 2, 2019 Author Share Posted January 2, 2019 Thanks. I'll just order a factory one then. I found one in my G20 that was the same as my G34. It is much tighter than the one that came in my 34. I need to get a replacement for my G20 now. Link to comment Share on other sites More sharing options...

Two separate issues. 1. If the gun shoots left, you have to adjust the sights, even if Rob Leatham shoots it into the center of the bull. It matters only where YOU shoot it - I'd adjust the sights so it shoots center. 2. How large is your group - at ten yards is interesting, but would be more interested in your 20 yard group size.

Yoakam Posted January 2, 2019 Author Share Posted January 2, 2019 Yeah...makes sense. I'll have to get over my complex. Next dry day I will back out to 20 yards and see what it looks like. I'm going to take some paper targets and get some pics as well. All this past weekend I had to wear rubber boots just to walk around my range. Policing brass in muddy water isn't very enjoyable.

DaFish Posted January 10, 2019 Share Posted January 10, 2019 Only one of 7 makes me think it's the gun. Mind you some folks claim they all shoot left... The G34 is long enough that a slow mo shot would show the slide has started to move before the bullet has left the barrel. I wonder if the locking block isn't square/flush perfectly? Huh. I guess maybe it could be a grip artifact. Do you shoot other guns w/longer barrels? Meanwhile I did install these in my G24 and G20.. https://www.glocktalk.com/members/t-r-graham.12922/ On a related front, I've just started shooting again after a few years away. And suddenly I feel I'm shooting left with the G20. A gun I believed was dead on the money when I'd stopped shooting. Weak left hand grip on my part? I'm wondering..

ima45dv8 Posted January 14, 2019 Share Posted January 14, 2019 Having the center pad of the first finger segment on the trigger is the conventional wisdom for most guns, but Glocks can be a little different. Try more finger in the trigger guard/on the trigger. Then try less. Link to comment Share on other sites More sharing options...
DianabolandDeadlifts Posted January 16, 2019 Share Posted January 16, 2019 More finger on trigger straightened me out as ima45dv8 suggests Link to comment Share on other sites More sharing options...
DB_Cooper Posted January 16, 2019 Share Posted January 16, 2019 I have the same shooting left issue with my G34.4 so it has become a safe queen. I mainly shoot my Canik TP9sfx and STI Edge. no problems hitting center of the target with those guns. Link to comment Share on other sites More sharing options...

From my experience, covering up poor trigger technique is never a good idea. I started out with a 34 and consistently shot left because I had a terrible grip and I was tensing up my firing hand and ripping on the trigger. I eventually learned to pull the trigger straight back and now I can accurately shoot pretty much any gun I'm handed. If the gun really isn't sighted in you should adjust the sights, otherwise learn to pull the Glock trigger straight back. Link to comment Share on other sites More sharing options...
OptimiStick Posted January 29, 2019 Share Posted January 29, 2019 (edited) I picked up a couple of gen 5 g34s with the new marksman barrels.... aside from them being surprisingly short chambers, the accuracy was not good. At all. I dropped in a KKM barrel and the difference is night and day. I did not experiment with loads at all - I was shooting my usual 147 gr. coated TC and RN. So who knows, maybe I could have found a more sympathetic load for the factory barrels - but I just didn’t mess with it. I’ve always had great results from KKM and this was no exeception. Trigger had nothing to do with it in my case. Edited January 29, 2019 by OptimiStick Link to comment Share on other sites More sharing options...

Look up “diagnostic target” in the google machine and print them out formyour range trip. I use these a LOT with students, friends, my son and even myself from time to time as we all get into some bad habits and need a tune up. Sounds like you need a little more finger on the trigger but see what the target says. Link to comment Share on other sites More sharing options...
danish Posted February 21, 2019 Share Posted February 21, 2019 I’ve shot thousands of rounds through my 34 and it always shoots left. Even with the RMR it shoots left. I dry fire consistently and cannot overcome it. Adjust your sights and shoot it. Link to comment Share on other sites More sharing options...
wanttolearn Posted March 8, 2019 Share Posted March 8, 2019 How interesting. I too have found myself chasing this issue, steadily adjusting the rear sight to accommodate. Of note, i've not experienced this phenomenon with any other pistol of which i can recall. I shoot dead on with a Sig P226, a Sig 2009, a S&W model 52 and a myriad of 1911s. This Glock 34 has proven to be a tougher platform for me to adapt to with respect to alignment. All in all I've been quite satisfied with stock function and accuracy. While i'm not a great fan of the quality of the trigger action or the grip angle. i've made my peace with them. I wonder if it's not these latter aspects which contribute to the phenomenon.

Marshal82 Posted March 8, 2019 Share Posted March 8, 2019 The locking block may not be the cause. The take down lever that locks on the barrel lug does play a big role, change that and re-test. Sometime a barrel change is needed as well. Link to comment Share on other sites More sharing options...

pxm142 Posted March 10, 2019 Share Posted March 10, 2019 I had a G17 that shot 8” left at 20 yds. I had plenty of other Glocks in my safe and never had the issue before. A couple other people shot it with the same results, so I began experimenting with different parts to correct it. I quickly discovered that is was in the upper, as swapping other uppers onto the G17 frame resulted in perfect hits. It got weird when I swapped barrels and slides. The slide worked great with other barrels, and the barrel worked great with other slides, but putting the two together, on any frame, resulted in the way left hits. Ultimately I didn’t want to spend any more money on replacing either part so I gave up on it and sold it to a buddy who drifted the sights to correct, but it looks terrible. Very weird that the factory parts didn’t like each other. Link to comment Share on other sites More sharing options...
rdinga Posted March 11, 2019 Share Posted March 11, 2019 I like Glocks and have owned a small herd over the years. A couple shoot head and shoulders above others. All of them shoot great. But there was this one 34 that I could not get to shoot. Different locking blocks, loads, sights, different barrel. Just never could warm up to this one. Not often but every now and then the gun needs to find a new home. Link to comment Share on other sites More sharing options...
