The STI Tac Master by ASG delivers a high quality gas blowback 1911 pistol at a great price. With great attention to detail and full metal construction, this GBB is a very accurate reproduction of the world famous 1911A1. The blowback is crisp and makes the gun a lot of fun to shoot. The rubberized material of the grip is very comfortable and adds a nice touch to the gun, as does the skeleton trigger. Another great feature is the built in tactical rail which allows the user to add tactical accessories such as a laser or flashlight. The metal magazine has a capacity of 24 rounds and holds a 12g CO2 cartridge. The gun shoots at a solid 328 FPS with 0.20g BBs, making it an ideal backup weapon or an awesome primary for indoor play. The STI Tac Master also features a beaver-tail safety and ambidextrous trigger safety.
