How fussy are Glocks ?

[Still alive]

As long as it's FMJ of some kind, no problem at all! Avoid lead reloads.

They are not fussy......

I shoot the cheapest ammo available and never had a problem.

This i have to say, i never had a malfunction from my 3 Glocks even with the cheapest ammo... JP.

Not at all. No issues in close to 5000 rounds of various brass cased ammo.

Glocks are very reliable.

Not fussy at all unless you have an aftermarket barrel in which case it's likely a match grade chamber, which will be fussy.

I've only had FTE with one batch of very anemic fiocchi 115 gr fmj. I had a Gen 3.5, Friend had a Gen 4 G19, we both had FTE. Same ammo also FTE in my HK.
Typically the Glocks eats everything.

I had a buddy who picked up some LRW Steel case ammo and he had issues with his aftermarket barrel.

I saw a video of a guy who managed to get a Glock to fire and cycle a 9mm round loaded with black powder (had to fill the case with 4f to get it to work). Pretty much says it all.

Actually it's not the Trigger upgrade that can possibly cause issues, it's messing with the firing pin spring (though some do mess with it to attempt to improve the trigger) that may cause light strikes.

You are correct... When I changed my connector I did change the firing pin spring. On the plus side, I have NO over travel, and my a Glock trigger now rivals that of my SA revolvers!

I had issues with the Blazer aluminum casings ejecting. I was told to use TMJ rounds in my 17 Gen 3 and have never has a problem since.

I had a couple of failure to feed from some old Norinco 230gr FMJ in my Gen3 G21, but I believe it was the old, second hand rounds with some poorly-seated bullets (too shallow, making round too large) that is to blame. No failures at all from North American factory rounds.

One recent note - I picked up some Barnaul a little while ago and even my brand new G19 wasn't reliable with it - it's definitely a hard primer issue

 

[xdmer]

Not fussy at all, I've put thousands of rounds through my G17 - all sorts of cheap and expensive stuff. No issues.

 

[r34skyline]

glocks arent picky on ammo. polygonal rifling doesn't from what i hear like excessive use of cast bullets.

 

[NAA]

Keep 'em clean & never found a Glock to be fussy at all.

NAA.

Run that ammo hard through your Glock, and if it starts to whine, be mean to it and shoot it some more.

 

[FreedomIsn'tFree]

I have a Gen 3 G17, Gen 3 G22, and 2 Gen 4 G17's. None of my Glocks have failed, in any way what so ever, with whatever ammo I shoot.

 

[King Kong]

Only thing you aren't supposed to use in a Glock is lead ammo (if that even exists anymore). Only metal jacket .

Had my first stovepipe with my G19 and it's LW barrel (first Glock malfunction ever) on the weekend with WW ammo during a rapid fire mag dump . Thought i had run the mag dry. I actually stared at it for a few seconds (need to practice my drills for that, but it's hard when it never happens), guess i need to buy an M&P for that.

That said, I have never cleaned or lubed the gun, just ran it right from the box since new.

Probably should do that...
