I have a brand new KZ 45 and had chance to shoot it yesterday.Or at least try to shoot it.It fails to feed at least 2 times from every mag.Both mags do the same thing.I tried full mags,down loaded mags,all the same.I am using PMC 230 grain and PMP 220 grain.Same results with both types.Gun was clean and well lubed but not overlubed.What is going on with this CUSTOM gun?
