Sorry so late to this thread, as I just happened on it. I've got 4 or maybe 5 of these Nagants. One of them I have modified extensively for use in slow-fire target shooting. It is not great, but not bad -but not great. I bought them at a time when they were going for around $40 in new, unissued condition with holster, lanyard and screwdriver. At the same time I bought them, I bought the conversion cyclinder which would allow shooting of .32acp. The cylinders require a fair bit of use to 'work in' but allow a far more common caliber. The .32acp round seems a bit more accurate than the 7.62 Nagant round, but I'd not done any kind of load work-up on the 7.62 rounds.
They are a 7 shot, which is kind of neat. They also gas-check the cylinder which adds a lot of poundage to the DA trigger pull. A previous poster claimed 10-15 lbs. I've never put it on a scale, but I would say it is all of that.
