The Remington LSWCHP +P load, a/k/a the FBI Load, is a very good load. My other choice would be the Speer Gold Dot135 gr. +P JHP for short barrels. Yes, there's a bit more recoil with the +P loads but I think it's worth it when carrying a snubby.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
