What's wrong with this Glock?

The extended mag not seated properly and bad ammo A Glock would shoot rocks if possible

Its the extended mag. Had the same problem with 2 pistols. Swapped out the extendo for the factory mag and the problem went away on both guns.

Prob limp wristing it causing it to jam? Just a guess

He is using cheap after market magazines and some will jam all the time. Always buy Glock or good name brand magazines.

Shit ammo.

The operator

limp wrist

Nothing. Shooter and ammo.

Limo wrist, crappy after market mags, looks like a .40, have to replace spring.

SAMS S - shooter A - ammo M - magazine S - system I’d reckon it’s one of the first 3
