Another filed test video in the series. This one is of the Umarex Walther PPK/S CO2 4.5mm BB pistol, I show you both my regular unmodified all black PPK/S and shoot it through my Chrony Chronograph with an averaged reading of 282 FPS, not bad considering the manufacturers claim is 295.
I also shoot 8 rounds with my stock Umarex PPK/S at a target to see what kind of accuracy I get, and just for fun I shoot a 15 round magazine into the same target with my modified fully-auto sliver slided PPK/S.
To finish things up, I slowdown the action just a bit using my high speed Casio camera to capture the blowback action of both my stock and modified Umarex Walther PPK's.
Enjoy my YouTube Video of my Umarex Walther PPK/S CO2 BB pistols getting Chronographed, shooting at a target and slowed down a bit with my High Speed Camera.
