I like to carry a 640-1 in a Galco IWB holster, tuck-n-go. With the J-hook, it is very easy and quick to wear and take off. Always at about 4-4:30 position.

Though at times I do carry a Sig p238 in my pocket. I use a Glaco pocket holster.

POCKET PROTECTOR HOLSTER: Galco Carry Lite Series at Galco

To me Galco is one of the top holster maker and these to holsters won't set you back like some of their other quality products. Carry concealed is about being comfortable. You don't want to sacrifice comfort for style, so both are no thrills holsters.
