Yes, the 1895 Nagants, used with proper 7.62x38r ammo, will require a SA-style extractor - an ejector rod. This is not due to the small rim...
The 'proper' ammo, even the mild target rounds and the Fiocchi ammo as well, actually extends into the barrel when fired (The chamber has no shoulder/rim stop.). This oddity makes the Nagant a gas-sealed revolver, capable (and, actually used) as a silenced weapon. The thin rim expands slightly upon discharge, requiring a rod to push them through the then too-small chamber exits. Once within the tapered chamber, they will fall out. Of course, the too-small cased .32 S&WL/H&R Magnums will expand and require 'help' too. Of course, in the heat of battle, that seventh round was probably appreciated, as they aren't rapidly reloaded.
I have seen a picture of one with a bayonet, too. Odd, but neat, little piece of Victorian engineering. Join us at Gunboards Nagant forum for loads of more info.
