The only thing I'll add to this debate goes to the accuracy issue. Some fixed sight .357 magnums are regulated for 158 gr. loads and some for 125 gr. loads. The heavier bullets shoot higher at typical self-defense ranges. Check yours and see what bullet weight it is regulated for.
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.
