I picked up a 351 PD a couple of days ago. Very impressive little gun.

I figured that I would see what it does in water penetration with the Speer short barrel 40 grain rounds. {looking for expansion mushroom}

filled a 64 oz plastic bottle with water, put it on it's side in the snow and fired a round directly into the center of the bottom.

Guess I have to gather some more water containers...or else build a grocery sack box that will hold at least two bags full of water.....bullet went right thru the bottle and took the cap with it. Gone.... lighter than anything I own for carry and 7 rounds of a wicked little bullet, with shooting muffs on, sounds like shooting any old 22. {does go thru a box of ammo quick, no recoil} I'm impressed

The only J frame gun that I haven't needed to change the grips on, because of the size of my hands and the recoil slamming the trigger guard into my middle finger.{lovin' it}
