csailer Posted September 21, 2015 Share Posted September 21, 2015 I've had a Glock 34 for a little more than a year now, with no replacement parts other than switching out a striker spring. What will break or need replacement? I don't want to have anything give way in a big match. Anyone have any experience with parts breaking? Thanks, Chris Link to comment Share on other sites More sharing options...
Poppa Bear Posted September 21, 2015 Share Posted September 21, 2015 The only part I have HAD to replace is an extractor. Had a case head separation that blew the magazine and the extractor out. Found all of the parts except the extractor. Otherwise I have common parts like extra trigger springs, recoil springs, connectors, triggers, as well as many other parts in my parts case. About the only things I do not have are barrels, frames, and locking blocks because all 4 Glocks are different models and calibers so those parts are not interchangeable.

rowdyb Posted September 21, 2015 Share Posted September 21, 2015 Trigger spring. Mag springs. Front sight. In a hard year running a 34 those are things I HAD to replace due to breakage or being totally worn out to the point of causing function issues.

obsessiveshooter Posted September 21, 2015 Share Posted September 21, 2015 The catch detent, or whatever you call it, on your magazines will wear out and can make them unreliable. That's more of a slow building problem than a sudden breakage though. Link to comment Share on other sites More sharing options...
bigtimelarry Posted September 21, 2015 Share Posted September 21, 2015 Change all the springs and pins every 8,000 rounds and you'll never have an issue. Put a new locking block in at 24,000 rounds.. Link to comment Share on other sites More sharing options...
BitchinCamaro Posted September 21, 2015 Share Posted September 21, 2015 Finally broke a trigger spring and ruined my day. Now all the coils get replaced once a season. My plunger safety is looking worked from dryfire, but I don't think it's going to "break". Link to comment Share on other sites More sharing options...
CDRODA396 Posted September 21, 2015 Share Posted September 21, 2015 Trigger Spring is about all I've ever seen "break." Link to comment Share on other sites More sharing options...
Dr Mitch Posted September 21, 2015 Share Posted September 21, 2015 I had one of the locking block pins break once. The one that sits over the slide release spring. That's been it for me, over about 23,000 rounds of minor PF. I have a friend who had the trigger pin break, and an extractor as well, on the same gun at the same match. It was a G24, with about 16k on it that year alone. Link to comment Share on other sites More sharing options...

chirpy Posted September 21, 2015 Share Posted September 21, 2015 Best advise I have heard is "a spare Glock 34"! With a spare you don't need to worry about replacing a part between stages if you have something break. Richard Link to comment Share on other sites More sharing options...

gallardo0311 Posted September 22, 2015 Share Posted September 22, 2015 I've broken multiple mag catch springs....... Buts that's due to practicing mag changes in dry fire Link to comment Share on other sites More sharing options...
Romans 13 4 Posted September 22, 2015 Share Posted September 22, 2015 Plunger safety, locking block pin and recoil springs are what I have personally seen fail or wear down to the point of needing replaced. There are only 30 some odd parts in a Glock, so other than the frame, slide and barrel I carry replacements. I shoot full house 40 loads as well.

Southpaw Posted September 22, 2015 Share Posted September 22, 2015 As said the trigger spring is the most common part to break. Only part I've ever had break on a Glock was a firing pin spacer sleeve. Gun still functioned fine with a crack in the spacer sleeve, only noticed it when I detail stripped it.

hceuterpe Posted September 22, 2015 Share Posted September 22, 2015 How many rounds you got through it so far? That's my only question, before I throw something in Link to comment Share on other sites More sharing options...

About the only things I do not have are barrels, frames, and locking blocks because all 4 Glocks are different models and calibers so those parts are not interchangeable. I saw that happen to a friend of mine, twice in the same night. We found the extractor the first time and I actually got it back in the slide without dis-assembly and that ain't easy. (I had never played with a Glock at that time.). Both times it was with Fiocchi brass that ruptured. I dissected some brass and found Fiocchi to be thinner than other brands where the brass is unsupported in a Glock chamber. While not a part failure it will be the end of your day without a replacement part. Link to comment Share on other sites More sharing options...
safeactionjackson Posted September 22, 2015 Share Posted September 22, 2015 Trigger spring, and slide stop (spring) are the most common failures. I've got a G34 and G17 (both gen4's) that both have 40K+ without issue and without replacing anything. I'll bring the G17gen4 to larger matches for spare parts and or a backup pistol.

Red Ryder Posted September 25, 2015 Share Posted September 25, 2015 Trigger spring broke once, but the recoil reset the trigger so I did not realize it right away. The trigger felt funny but the gun still fired. After I finished the stage, I looked at the gun apart at the safe table and replaced the spring, all in under 2 minutes. Got to respect that simplicity from a curtain rod maker! Link to comment Share on other sites More sharing options...

9x45 Posted December 14, 2015 Share Posted December 14, 2015 Since 92, over 350,000 rounds thru various Glocks, about 170,000 on my oldest 2 pin G17, and experienced the following breakages: trigger reset springs slide lock spring (little L shaped spring in the frame) slide lock itself (just wore the tab paper thin) slide stop lever (spring went dead) locking block pin walking out (didn't break) firing pin spring (not broken, light strikes) chipped extractor on a G21 (loaned it to a buddy who ran several matches and loaded it by putting a round in the chamber first) sheared the barrel lug of on that same G21 cracked slides on the G17 (twice, due to running over 20,000 rounds of +P+) The best spare parts kit is a 2nd gun... new firing pin spring length Link to comment Share on other sites More sharing options...
ZackJones Posted December 20, 2015 Share Posted December 20, 2015 I have a gen 2 model 22 that recently broke the locking block. It also had a broken ejector. I had the Glock armored go through it at the recent GSSF match and he replaced both parts as well as replacing the trigger spring and guide rod/recoil spring.
