Exactly. Or faulty cheap low bid ammo.
My 2 have cycled 1000’s of rounds and keep on shooting.
Do the .45 GAP models have the unsupported chamber, like the .40SW Glock 22s?
Never had a problem with any of my Glocks.
Reliable as hell.
I’ve got three, and thrown hand loads, cheap steel jacketed foreign ammo, +P, etc through them. Never a single solitary failure.
Sometimes I think I could put a rock into the chamber and they would fire it just fine....
