Hi Mas, Just got a 640-1 at the gun show. Tried Remington Golden Saber -1200 fps, Winchester PDX1 Defender -1325 fps, and Hornady Critical Defense -1500 fps. They all kick hard so I'm thinking go big with the fastest. (I know the velocity will be reduced in my snub nose). Now I see Double Tap's bonded defense round at - 1605 fps (1425fps / 1 7/8" S&W) Is this too much pressure for the Stainless J-frame? Thanks Wanna kill these ads? We can help!
