GIO Posted July 23, 2016 Share Posted July 23, 2016 I am new to Glocks and was hoping for some input. I like having spare parts around for all of my firearms and would like to know what is most likely to break or need routine replacement on a Glock 17. I know they are super reliable but everything has a weakness. Thoughts? Thank you in advance Link to comment Share on other sites More sharing options...
BrocDowns Posted July 23, 2016 Share Posted July 23, 2016 just keep extra springs for the striker and the other trigger springs, also an extra guide rod and spring and extra striker and extractor, also if you use fiber optic front sight carry plenty of extra fiber a way to cut it and a lighter to heat up "bulb" the ends to make it stay in the front sight.

That about sums it up maybe some firing spring cups for that rare instance you have to change the striker spring. People have a tendency to launch them across the room when changing that. At the end of the day there isn't much thats going to break if anything, and I've see a lot of rounds come out of a lot of different glocks.

Daft Posted July 24, 2016 Share Posted July 24, 2016 Curious as well. I never carry extra springs. Mags, yes. Link to comment Share on other sites More sharing options...
9x45 Posted July 24, 2016 Share Posted July 24, 2016 In my experience of running Glocks for competition and carry, since 92, a couple of trigger reset springs, one time a chipped extractor, sheared a barrel lug off of a G21 after about 125K rounds, cracked 2 slides on a G17, but mostly due to running +P+ rounds more than 30K, recoil spring assemblies about every 3 years, had a trigger pin fall out once, firing pin springs get weak after so many rounds, couple of mag spring replacements, What I keep in my carry Glocks, shoved up under the butt plug, is a spare extractor and trigger reset spring. You can reset a broken trigger spring manually but a cracked extractor turns it into a single shot, Link to comment Share on other sites More sharing options...

9x45 Posted July 24, 2016 Share Posted July 24, 2016 GIO, I'm sure there are lots of guys who have run at least as many rounds as I have. My oldest 2 pin long rail G17 just turned 200,000 miles, and another 200,000 thru all the other Glocks, still as accurate as day one. Now my first G19 didn't fair as well from the car fire. Slide got so tweaked you can't remove the barrel, and the frame is pretty twisted up also. New small parts and springs, 30 days with the frame in baking soda to get rid of the smell. It still runs but I don't use it anymore. Link to comment Share on other sites More sharing options...

RangerTrace Posted July 24, 2016 Share Posted July 24, 2016 Only part I've ever had break was the little wire/spring that gives the slide release tension. Turned it into a singe shot, really quick!! Link to comment Share on other sites More sharing options...
dsmw5142 Posted July 24, 2016 Share Posted July 24, 2016 Yeah me too. I've also had a trigger pin come out in two pieces, broken in half. Once I had the tip chip off an after market striker. I've seen a couple of broken trigger springs on guns and had one myself. Other than that, some new F.O. now and then, although I think I've only lost it once. If you install it right it usually hangs on pretty good. Overall they take a silly amount of abuse and keep running. Link to comment Share on other sites More sharing options...
hildy19 Posted July 25, 2016 Share Posted July 25, 2016 From looking around I think there was a post similar to this and it seemed fairly reasonable to keep a stock of all the internal parts. $50 to have everything if I recall correctly. Have extra springs guide rod Extractor Etc Or just get another gun? Seems like a good excuse to buy a new one. "Just in case" Link to comment Share on other sites More sharing options...
aceinyerface Posted July 25, 2016 Share Posted July 25, 2016 Brass shards and assorted crud will accumulate in the firing pin block and firing pin channel by the hole, over thousands of rounds it will eventually stop working, so clean it. If you ceracoat the slide, most likely you will ruin the least known about part, the plastic sleeve in the firing pin channel. Aside from that, not loc-titeing your front sight post will get you an unscheduled point shooting practice session. Get involved in the GSSF and they have armorers that will change springs for you at the match for free. The biggest problem with Glocks is that they don't deal with case head separations very well.

9x45 Posted July 25, 2016 Share Posted July 25, 2016 Most guns don't deal with case head separation (not KaBooms) very well, but at least in a Glock it won't destroy the gun. KaBooms, on the other hand, tend to fair way better in a Glock, because it blows most of the guts down the down thru the magwell, unlike a 1911, that wants to send the hammer toward your face, from personal experience, as I've blown up a couple of each, along with a S&W 59 and an H&K P9 chasing Major 9mm. I haven't used thread lockers for more than 25 years, but rather use Permatex # 2B. It never fully cures, but is easily removable when you change sights from one gun to another. Over 300 sight set installs, and not one came loose. For competition, the best spare part is another Glock of the same setup, 3 is even better. Yea, forgot about the little L shaped slide lock retainer spring, if that breaks, the whole upper will fall off. Early Glocks had a narrow version, the new one seems to last.

CaptainOverkill Posted July 25, 2016 Share Posted July 25, 2016 Based on my experience and a few guys I shoot with, this is what I've seen wear out and/or break: Recoil springs (wear out over time) Trigger springs (break) Slide release (spring wears out/breaks) Slide stop (spring wears out and will no longer lock open on an empty mag) Striker (tip breaks off) Ejector (tip broke off - replaced the whole trigger housing) Striker channel liner (as mentioned above, if the slide gets cerakoted this needs to be replaced) Slides (cracked by hard use, breach face can break from dry fire) An extractor is probably a good part to keep on hand as well. I've never worn one out, but I can see it happening. Link to comment Share on other sites More sharing options...
steven785 Posted December 29, 2016 Share Posted December 29, 2016 I have broken both the magazine release spring and trigger s spring. I also carry an extra front sight and fiber rods just in case. Link to comment Share on other sites More sharing options...

Made it through 5 stages and never had a problem. Link to comment Share on other sites More sharing options...
polymerfeelsweirdman Posted January 6, 2017 Share Posted January 6, 2017 Hah nice solution if I had a pin break or walk and get lost I'd be tempted to put an allen wrench in and tape the short side to the frame Link to comment Share on other sites More sharing options...
Distant Thunder Posted January 7, 2017 Share Posted January 7, 2017 After years of shooting GSSF matches about the only parts breakage I've heard of in any numbers even approaching significance is the trigger return spring and that has still been a rarity. Now this is with Gen 3 and earlier models. I have virtually no first hand knowledge of the Gen 4 models. Link to comment Share on other sites More sharing options...
buckley Posted January 7, 2017 Share Posted January 7, 2017 The suggestions look pretty good. I'd add magazine springs. I did about 15k rounds through one magazine, usually 5 rounds at a time. The mag spring got a little weak after that. Link to comment Share on other sites More sharing options...

sitw Posted February 19, 2017 Share Posted February 19, 2017 Things I have seen actually break and fail, rare, but have seen it: Trigger spring Striker Extractor Things I have seen wear on high round count guns: All Springs - just like any other gun, they set over time and need replaced. Keep a spare trigger, recoil, striker, and extractor spring on hand. Extractor Link to comment Share on other sites More sharing options...
