for under $100, this H&K USP double action, Non-blowback, Co2 steel BB replica air pistol is a well made, and realistic looking semi-auto air pistol! it is desgned around a full size magazine that holds the co2 & ammunition, this BB pistol has enough power to punch holes in soup cans, and accuracy is as good as one expects from a smooth bore barrel and roundball ammo.
