Believe it or not, my Semi Compact jammed, in mid recoil, first time out, after only a few Rounds

Got it home and was able to get it apart
Put everything back together again, but it wouldn't fire

Turned-out, the Firing Pin Block Lifter had broke in the Sear Cage

Whether it broke during recoil and jammed the Slide back
Or it jammed the Slide and I broke it off when I took the Pistol apart .... no telling
Even CZ-KC couldn't figure it out .... or how it could have jammed in the first-place

Needless to say; they covered the whole thing
Hope you get yous sorted-out
