Help with GLOCK failure.

[PolishMike]

Almost every single Glock we have had brought in with issues has had an aftermarket guide rod. Every time we put the stock one back in the gun magically works again.

Any particular issues? Thanks.

Failure to feeds mostly. Some failure to ejects too

Its a pretty well known issue but people always want blingy ****.

Just change the rsa every 2500 rounds for Gen 3 and 5000 for Gen 4 and the gun will keep working.

Lol. Very true. Thanks PolishMike.

Thanks for the tip Mike, quick question what's RSA? I am randomly guessing....the extractor? I get my first glock in 23.5Hrs.....

Should I clean it? or leave it be before firing?
I know I will run patches of CLP through the barrel though. Any tips would be appreciated.

ya i've never seen a shooting game where the characters use anything close to a thumbs forward grip. I dunno why, but I get the idea that most IPSC shooters use thumbs forward for a reason other than that it's in video games, lol.

One observation that I've made is that thumbs-forward allows more of the heel of the shooter's hand to make contact with the pistol frame/grip. Locking the strong side thumb down with the support side thumb raises the heel of the hand away from the pistol. Don't know if that's the reason or not.

Something I haven't seen mentioned is the possibility that the OP's thumbs-forward grip may have allowed the support hand thumb, the firing hand thumb, or even both to contact the slide, retarding extraction and causing this malfunction. I have observed this when training shooters, although not often.

I just mapped out your location, N. Fontucky. Sounds like you're in CA. Not sure how you have "newish factory 15 round mags" with this gun. Suggest you be careful.

Turby

Yes, it's Fontana

I rebuild all my mags after a certain amount of rounds, depending on the firearm. This mag has under 1k and is less than a year old, thus the newish description. Not too worried about being "careful" as they're legal and I even still have the original receipts from the 90's, but I do see your point thanks! I do notice shady people/comments regarding people and their preban claims.

Still no pics up, but I noticed on our spent brass, about half the rounds have a crease in the brass near where the bullet seats. Not sure if it's my pistol or his causing this. I'll check my brass next week when I go back to the range.
Still working on taking and posting pics to help describe whats going on.

Thanks again for all the helpful input.

Glad you pointed this out. My thumbs were clear of the slide. 9mmepiphany game me some great advice that I tried out. Long story short my thumbs used to press on the slide causing me inconsistency and bad groups. I change my grip and thumbs were very clear of slide. I'm thinking I limp wristed...

That is probably where the brass impacts the slide during ejection.

Change the recoil spring assembly when it quits working, except for a carry gun. I went over 40,000 rounds on a G17 before the spring got weak, by the straight up trigger pull test.

Just did a little homework, my results: Federal Champion 9mm is probably the worst choice for Glocks it's very weak ammo. UMC and WWB are bulk/cheap ammo, self explanatory.

Go right ahead and buy the expensive 9mm ammo. I haven't had any problems at all with Fed Wwb Or Remington and if you feel that 115gr is a weak load just start shooting with 147gr then

The truth is that some factory 9mm does actually suck and may not run well in certain guns.

RSA = Recoil Spring Assembly
