A quick overview of the G&G GTP9-DST Gas Blowback Pistol available at Gunfire... "After the warm reception of the GTP-9 airsoft pistol replica, the Taiwanese manufacturer G&G Armament introduces a new version of this model - the GTP9-DST pistol replica. The new version has a metal slide (MS - Metal Slide), a high-flow gas valve with a microfilter, a specially designed cylinder valve with the Whirl Cylinder technology, and a blow-back system. Noteworthy is also a light, polymer frame and a well-thought-out design that make up a very functional pistol for airsoft games. In the set with the replica, we receive a 22 BBs green gas magazine and a solid, polymer transport case."
