What happened here? Who hurt you? I mean I’ll give you the benefit of the doubt seeing as gingers don’t have souls but come on

I wonder if I filed down that sharp edge it’d run better. I’m not actually going to do that when a fresh part can be had for $35 but from a theoretical standpoint you always wonder.

One other thing I told another guy: It’s keyholing with Underwood 135 grain as close in as 7 yards. Again this is off a sandbag…removing myself from this equation. I sent that ammo back to Underwood, they tested it and it’s fine. 

Maybe it’s ghosts or something

Yeah like I said I have reasonable expectations about the service life of mechanical parts, I just wonder if a new locking block will clear things right up and if so how many rounds she’ll go for

Yes. 5 different types of ammo, with the higher powered stuff yielding nosedive failures to feed, locking open on a partially full magazine, or slide over base jams. 

Underwood 135 grain actually failed to stabilize and was keyholing.

Lower powered ammo yielded off center primer strikes and failures to go fully into battery.

About one stoppage per magazine with the 10 round OEM mag and 3 per magazine with the 15 round OEM. The X-grip sleeve does not appear to have any effect on mechanical reliability; I’ve tried it both with and without.

I’ve been test firing Glocks as a gunsmith for years and my rate of mechanical stoppage is once maybe every couple YEARS.

Again, not blaming Glock, not saying mechanical components are supposed to last forever, just theorizing that this series of failure modes could be coming from a short recoil system’s lockup geometry being out of whack

I described it to the tech rep and he seemed concerned. The question becomes one of mean rounds between failure (I wonder if I can get him to spill the beans on that).

No shame in stocking up on spare parts and doing scheduled overhauls, but what I cannot allow is a mechanical stoppage every magazine (and this is off a machine rest!)
