The HECKLER AND KOCH VP9 is a 9x19mm caliber semi-automatic recoil loader from Umarex; based on a modified H&K P-30 recoiling barrel. This 4.5 mm (.177) BB with original markings on the slide and on the handle is made from impact-resistant polymer with a sturdy metal carriage. True to the original, the structured grip does a great job when the blowback recoils with each shot.
