Not having seen too many self defense shots needing to be made at 100 yards. Not sure I would even know what I was shooting at that distance. I carry a Ruger SP101 .357mag, 2 1/4 in barrel. Not too heavy, easily concealable and accurate at what I would consider self defense distances. If I can't get at least one round out of 5 in the stop zone I really need more range time. Is it my favorite handgun, no, I truly enjoy shooting the 1911s but rarely carry them, so far, so good.
