the vp70 is a 9x19mm parabellum handgun made by heckler &amp; koch, a german gun company. it was the first polymer-framed pistol ever made. it was first made 1970, 12 years before the glock. being polymer-framed means that it was much lighter than metal-framed handguns. it can be attached with a buttstock, and doing so will allow the gun to fire in 3-shot bursts. otherwise, the gun only fires in semi-automatic mode.
