These were all bought new and had under 1000 rounds fired
HK USP 45, trigger broke
Walther P22 X2
Ruger MKIII, Magazine disconect
Marlin 22 rifle, return spring
Kimber Pro Covert II, bad feed ramp, shipped with the wrong recoil spring, needed a different extractor, magazine was thrown over a burm
Chales Daly Semi auto 12 guage, a plastic bushing mushroomed out after 20 shells.
Stoeger pump 12 guage, shipped with a bent feed spoon
And the worst, a Colt Gunsite 1911. Both sights fell off with less than 200 rounds. The slide was improperly machined.
The only guns I have owned that are 100%.... Glocks.
