They have one of them Double Taps up to Norpoint Shooting Range, The cost was about $450. I'll stick with my Bond Derringer in 45LC/410 loaded with 2 1/2" buckshot for close encounters.
I didn't like anything about the Double Tap. Most of the time I carry a 38 + P S&W or a Rossi stainless 971 in 357mag. For the big cities I carry my Colt Combat Commander. I'm a firm believer that you need enough fire power to stop any unwanted threats against your life. The Double Tap has enough power, but I don't like the package it's in.
