Description: The Umarex H&K P30 AEP Airsoft Gun is mostly comprised of plastic. This airsoft pistol is powered by four AAA batteries, which is installed in the grip. This model features a grip safety, which is not a feature of the real P30 firearm, but it is a welcome addition to a entry level gun designed for beginners. The plastic slide cycles realistically, along with a spring loaded hammer. A switch located in the trigger guard allows you to change the firing modes between semi automatic and fully automatic. Keep in mind that this product is not skirmish worthy, but is a great prop for film/movies or as a decorative set piece.
