Check out the XDs by Springfield.

I’ve got the Springfield XDs in .45 carried as a back up in a De Santis ankle holster. Can’t beat it while driving. A support strap over the calf, `sheepskin’ lining—I forget it’s there. They make a nifty mag carrier too for the right ankle.
It’s a little too much to conceal with blue jeans so I wear khaki trousers.
