Wish I could be positive about the Kahr/Auto Ordnance M1 repops , but the one I had( bought it new) came with a magazine that had a small hole rusted through it (reblued too, fed fine though), some rust in the bore, removal left no visable pitting,I've seen the same effect when shooting copper plated steel jackets,and although she functioned fine despite trying different ammo it wouldn't put 3 shots at 50 yards within 6 inches of each other.Not even by accident.One carbine doesn't make a trend, but mine was awful.
