I don't own a 325, but do own a 2" 327 which is similar in weight but kicks harder with full-tilt boogie 357 ammo. It came with wooden finger-groove grips which work just fine and don't hurt my hand. I cannot see why a 325 would be all that brutal. And yes, the standard round-butt N-frame stocks should work just fine.
I also wanted to add that I shoot a 629PC 2 5/8" in 44Mag which came with a wooden boot-style grip, exposes the backstrap and leaves your pinky dangling. While heavier, the 44Mag recoils substantially. I find that I can shoot it fairly accurately with the OEM stocks although I've altered my grip technique a little with that particular gun, and if I'm going to shoot more than about 15-20 rounds at a given session I prefer to wear a glove on my strong-hand.
