About half of the time I carry my S&W J-frame lightweight revolver (642, 38 Special). I carry this in my right front pocket in a Desantis pocket holster. It's very convenient. Just pop it in your pocket and go. I throw a 6 round reload on a
Bianchi Speed Strip in another pocket. Once in a while, I'll put the J-frame in a jacket pocket. I don't feel it's very secure though. I worry it will fall out, but it's not a bad way to carry just to walk across the street or something.
The other half of the time I carry a Colt CCO lightweight 1911, IWB (right, rear, about 4:30) in a Milt Sparks Summer Special. I put another 8 round mag in knife pouch on the left side of the belt. That gives me 15 rounds of 45ACP leaves all my pockets free for stuff (like keys and a small flashlight).
The 1911 actually conceals better and is often more comfortable. If I'm driving, it's easier to get to. A gun in a front pants pocket is difficult to draw when sitting and about impossible to draw with a seatbelt on. The only drawback to IWB for me is it takes longer to put on the belt, holster, mag pouch, holster the gun.
I carry the 1911 with a round chambered, hammer cocked, safety on. I never had a safety disengage accidentally and even if it did, the 1911 has a second grip safety. I would never put anything in the trigger guard of any of my guns.
I actually prefer a revolver for CCW for reliability reasons. I don't 100% trust magazines to always feed properly. I'm not 100% confortable with just 5 rounds of 38 Special plus reload though either. Also with speed strips, the revolver isn't as quick to reload as the semi. I need to try a larger, heavier revolver in .357 IWB one day and see how I like it. Or maybe I just need to try the J-frame IWB.
