My wife spent four years on active duty with the Army and several years in the Army Reserves (93P) so she is very familiar with the M-16. I keep a couple Ar's around the house in case things get really bad, but she prefers a revolver for self defense and keeps a 649 in her car and a 442 in the night stand. I keep a few revolvers around the house for her and a G-21 in the coffee table. She also has a Grendel R-31 (sn 997) and a Citori Micro, but they stay in a safe. She knows how to use them all, so I try not to make her angry.
