5 fps! I’ve never ever found or heard about something that minimal over these types of a substantial sample measurement.

forty S&W. In actual fact, the .forty S&W was derived from these decreased recoil loads and simply works by using a shorter circumstance. Fairly much any with the quality defensive 10mm ammo you’ll see on the shelf is “comprehensive energy.”
