I'm a retired LEO, and I'm old enough to have been issued, and required to carry a revolver. As such, I'm trained in it. As one of above the posters stated, "lot's of choices, and all S&W". Great advice right there. My choices would be a three inch 65, or 13 (if you can find one) 2 3/4 66 or 19, or what I have currently in the safe, a L Comp. IWB holster, two speed loaders and your set. If you have to carry 7 rounds max I'd make sure they were big bullets, and a 1911 with standard pressure HP's would work fine. The old FBI load of 158 grains +P SWCHP will still get the job done in these revolvers as even in a L Frame a 125 grain magnum's recoil is a bit more than any 9mm load most of us are used too.
