Lewis,
I have had a S&W 36 Chief blued (.38spl) 5 shot revolver for many years as my ccw, but found I was uncomfortable wearing it with summer clothes. I bought a Ruger LCP II a couple of months ago and found it to be better to carry in lightweight clothes (usually shorts and not much else). I wanted to get the LCP II in .380 acp but it was sold out in the local stores, so I got the LCP II in 22lr and ordered another in .380 when they become available again. Its quite comfortable in lightweight shorts. Whether a .22lr is adequate for ccw is a whole other discussion. The ballistic tests for purpose made .22lr ccw ammo lead me to believe it is adequate, although not the best. In any case, I am waiting to get the LCP II in .380acp.
