With one or two exceptions, I have kept all the guns that "work for me." However, I can certainly see why one might keep only a certain number of guns to meet specific needs.
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.
