I have seen a few of the Swedish Nagants at Gunshows over the years, and they are very beautiful Revolvers.
Of course the market eventually was flooded with the C.C.C.P. versions, and, those depresssed me. They have tended to be very reasonably priced even when in almost mint condition.
The pre 'revolution' Russian Czarist era ones do not depress me, but they tend to be priced a lot higher than the C.C.C.P. ones and or have been re-stamped and poorly cared for in how things went over there.
I would own a Swdeish one though, they have a very nice mood to them, and their fit and finish is superb.
