g. willikers is correct. I will add that standard pressure 147 grain ammo recoil seems very soft to shoot to me. There are both range/practice and SD type 147 grain ammo available. One standard pressure 147 grain type that I would not recommend if you're looking for light recoil is the Speer Lawman training ammo. This is fine ammo, I have used a bunch, but it is intentionally loaded to duplicate duty ammo specs and is a little warmer than other 147 I have used. For instance, 147 grain Lawman displays more velocity, and of course recoil, than the Federal 147 grain +P HST duty ammo..........
