Some Makarovs in 9x18 have been classified as C&R, as have
some models of the CZ-50.
I have an East German Mak purchased as a C&R from
AIM Surplus that is an excellent choice for CCW. With
the Barnaul ammo, it's been very accurate and utterly
reliable.
I have no experience with the CZ-50, but I would suppose
that like all CZ products it is a well-made firearm.
