despite its blunt 45 gr bullet's having lost 300 of its original 2600 fps. It knocks them on their asses,with good chest hits, and they can RARELY get up again. The 356 tsw has 2200 fps, 55 grs, the Split Nose 3 segment advantage, and 2.5x the frontal area of the .22 bullet. It is a very mean load, considering it's 6 hit per second controlable, in a 19 oz, 6.3" long pocket pistol. It makes a .40 Kahr look pretty sick, especially the 180 gr version.
