What I'm using now is an inside the waistband leather holster with a spring clip. The clip slips over the fabric of the trousers, belt goes over the whole shebang, it's almost invisible.

I normally carry a full size "K" frame revolver IWB, but there are certain social occasions where one doesn't want to take any chance of printing or letting folks know you are carrying, that's when the Ruger LCR cairried inside the waistband is perfect.

The holster I got I actually found at a flea market, but it is a quality one made by Backwoods Leather in Portsmouth, Va. They set up at gun shows all over the Tidewater area..

And welcome to the Smith and Wesson Forum, old friend!
