I have both & agree with the others here. Get both!
but get the Cz52 first. Much easier to find ammo for.
The Nagant should be around a while, the last batch that was imported took a while to sell because of the lack of ammo & their overall weirdness. You can shoot .32 S&W or .32 H&R mag out of them but the brass ends up funny looking. The Fiocchi is spotty in availiability & is $$$$. Bertram makes brass but pricewise you'd be better off with the Fiocchi. I have heard rumors that Starline is going to make 7.62x38R brass, if so then
. .32-20 brass can be made to work also.
The double-action trigger pull is almost funny in how stiff it is. Not just stiff but notchy because it cams the cylinder forward at the last instant. Works _much_ better for quick point & shoot work..."Great Lenin's ghost!! There's a a couple of fascist running dogs coming right for me!"
The trigger pull on the Cz52 is stout also but nowhere near the level of the M95. The sights are tiny but she's a service pistol, not a safe queen target pistol. Upgrade the recoil spring to the Wolff #16.5 or #18.5 spring. The stock #14.5 spring really lets the slide bounce around. DO NOT!!!!! dryfire it, you _will_ break the firing pin. Makarov.com
