Jer, I also prefer a hammer that I can cock when I want to, for a higher level of accuracy. Many holsters are designed to cover the exposed hammer.
I too prefer revolvers, J frame Airweights, for pocket carry. The Airweight frame is made of aluminum, and substantially lighter in weight than traditional steel frames.
Having said that, I find many situations where I need something very small, especially in the summer time. For those times, I find the North American Arms .22 Magnum five shot revolver to be invaluable. It fits in the palm of your hand, is quite reliable, kicks like a mule, and sounds like a .38 going off. I've carried mine in the pocket of my swim trunks while walking shirtless on the beach, when any other gun would be easily noticed, and drag your shorts to your ankles. Some will say the caliber is too small, but it's better than a knife, or no gun at all, for those times when size does matter.
