OK, I know this would be expensive to do, IF you could find someone to do it....
Would it be possible to swap a 7.62x25 barrel into a 9mm CZ-100 and have a really cool one of a kind super-penetrating carry gun?
Case heads are the same, Max OAL is really close (1.175" for the 7.62 and 1.169" for the 9mm)... What do you think? Would you buy one if it was available?
