I've been a fan of the Tokarev for a long time. My own is a Romanian. I am interested in the yugo, and it may be a future purchase.
My Romanian is a useful field pistol...great for backpacking, as the weight is reasonable and it is fairly small and flat. I find that the flat trajectory of the 7.62x25 makes hits at even 100yds pretty easy.
Ammo is very cheap, and I have a sealed 1200rd spam can in my basement right now.
