You made me take them off to check the frame.....and it's perfect! They fit so snug I had to thread the screw in from the wrong side and pull to remove the one.
As for feel, they are similar to the bantam grip, maybe a slight bit wider in the hand. I don't care for rubber grips with a pocket/ankle gun, which mine is. They have a slight feel of texture on them so it grabs your sweaty hand, but is not abrasive. Plus they look cool....
