All the problem guns ive seen and handled lately! Dealer dropped off a bi metal champion loaded that was new in the box he got on trade and was considering keeping for himself for my buddy and I to run some ammo through. First i have to say that thing was the most accurate .45 auto ive ever seen. I shot some loads into 3/4s of an inch and the worse did 1.5. But it was another jamamatic and about every 4 mag. it wouldnt lock the slide back it jammed and failed to stay back with sprin. mags and wilsons and ed browns so it wasnt the mags. Seems like everyone ive shot lately is a problem child.
