mines such a cream puff i hope i never find out!

for some reason i thought it was an 82 but i looked up 82 & 83 online and it came back that 82's are the military service model and 83's are commercial, after i posted the pic i see right on the slide it's an 82 in 32NAA ... ?

i tried to contact CZ for any info / literature on the model / chambering but no reply

quite a few make-overs on GB, some interesting, lots of candidates for make-overs too
