To compliment the Walther PPS firearm, Umarex offers an officially licensed versiona BB action pistol with realistic blowback action (meaning the slide recoils). Its drop-free magazine holds 18 rounds of .177 spherical steel otherwise known as BBs. It’s assembled with metal parts giving it a weight within ounces of the firearm. The PPS action pistol has a polymer frame that’s designed with a CO2 capsule charging tool ingeniously incorporated into the backstrap. Just remove the back strap and the spring-loaded hex key emerges so you can conveniently charge your action pistol or remove empty CO2 cartridges. While PPS stands for Police Pistol Slim, this semi-auto replica airgun isn’t short on features. It’s a repeater with low profile tactical sights, a metal barrel, an integrated under-muzzle Weaver rail, and the authentic Walther paddle magazine release that traditional Walther owners know and love.
