The 1895 Nagant revolver is definitely a fun little piece, but it's fairly expensive to shoot, although .32 conversion cylinders are available, and it's possible to fire .32S&W Longs, although the cases will bulge slightly. I have one of my own, and it's been a hoot at the range.
Here's the Gunboards
Nagant Forum. Lots of great information there.
You might also want to pick up a Mosin Nagant (or three) rifle; they're cheap, strong, packs a punch, and there's a plethora of them to collect. A Mosin Nagant M91/30 was what started my intense collecting habits, and Mosinitis is a pleasantly uncurable affliction. For hunting the 7.62x54R is an excellent cartridge, and is used regularly by many to take everything from boar to elk. There are at least a few Gunboards members who have taken black bear with their Mosin Nagants, and FWIU the rifles are popular in Europe for bear & large-game hunting as well. Mosins are capable of great accuracy (especially Finnish MNs), and they make great camp rifles (especially the carbines).
But as for handguns, I'll suggest the Makarov, FEG PA-63, or CZ-82 in 9x18mm, and a Tokarev (Russian, Polish or Norinco preferrably) & CZ-52 in 7.62x25mm.
Makarovs & the PA-63 in particular are very easy to carry & find ammunition for, have a decent amount of punch, and along with the Tokarev, are extremely reliable & affordable (ranging between $150-$250).
I carry my Norinco M213 (Tokarev-clone) 9mm every day, and it too is very easy to conceal, even though it's a full-size autoloader. I particularly like Tokarevs because they exhibit AK-like reliability, are extremely simple, and are acceptably accurate. Of the many handguns I've fired, the Tokarev makes accurate Mozambique-drills almost effortless.
Still, I'd prefer something a little smaller for concealed-carry, and the Makarov or PA-63 would fit the bill nicely; but I'll still utilize the Norinco 213 for open-carry, which I do frequently.
Have you considered the
Zastava M88? It's based on the Tokarev design, and comes in either 9mm or .40S&W.
