HI: 1525So that's pretty much spot-on, and likely would have averaged exactly at the box-flap numbers out of a 4.5" gun like a Glock 17.
HI: 1348As you can see, despite having three quarters of an inch more barrel length, the average velocity was still 50fps shy of what was measured at the box flap. Further, the somewhat erratic velocities common to hot-loaded, light-for-caliber pistol bullets were even more noticeable here than in the Inceptor.
HI: 2090Well, no reason to doubt that it would have matched the velocity claims when fired from the typical 4"-4.5" service pistol. It was loud, but recoil was minimal. Check out that Extreme Spread, though... The fastest and slowest rounds varied by almost 100fps in the same magazine!
Tune in for the next segment, where they'll get shot at, into, and through things, to see how well the claims of terminal effectiveness match reality.
