Hudson Tokarev TT-33 - a bit hard to get
KSC CZ-75 (czech gun, but you can pass it off in a russian kit as it was a eastern bloc weapon)
you might want to try a Cougar or M1934 (they kinda resemble a Makarov... or at least, the closest thing to it.)
as far as i know there arent any airsoft makarovs out there
for a russian kit you're probably better off with a 1911 or a glock - just try to go for a spetznas kit in order to explain it
