I'd also suggest the NOS Polish Tokarov & lots of surplus ammo!
Second to that would be the Norinco 1911, heck of a deal with Canada Ammo for a pistol & 1000 rounds of 45... Problem is, after those 1000 rounds run out, the 45 ammo is pricey...
Third, if you don't care that it's a 22LR, the M93 clone of the Woodsman is a great gun & ammo would be cheap!
Fourth, have a look at some of the Glock deals, for a little more, you would be stepping into a great gun...
Cheers
Jay
P.S. I have a Tok, Norinco 1911 (on the way) and a Glock, along with the Advantage Arms conversion kit for the Glock. Lots of options for some fun!
