Critical Defense
The only thing I know is that before this round was developed for 2" snubs ,the speed of a hollow point was very low for most bullet types. In some of the published velocity test in the gun mags. 1000 fps. is nothing to sneeze at from the 110 Plus- P 38sp. load in the Critical Defense. This is enough speed for expansion and penetration from snubs, where this had been a real problem.
