G19X meets Gen5 – the GLOCK 45 is the black version of a crossover Airsoft Pistol that combines the full-sized frame of the G17 with the compact slide of the G19. The front serrations on the slide and enhanced grip make this a typical Gen5 Airsoft pistol. The G45, a gas-powered airsoft version with a maximum energy of 1 joule, features a Shoot-Up that is adjustable from the outside, a powerful blowback and a heavy metal slide. With its Weaver rail for tactical accessories and ambidextrous slide stop lever this is an ideal backup Airsoft pistol.
