Capable of launching .177 caliber BBs to speeds up to 290 FPS, the Umarex Gen 5 Glock 17 MOS Half Blowback BB Pistol is an affordable training tool. It has correct ergonomics and is constructed out of polymer and metal to mimic its firearm counterpart. You’ll love its 17 round magazine capacity, polymer frame, and metal slide. It is powered by a CO2 cartridge and has half blowback to simulate recoil for more realistic training. This Modular Optic System (MOS) pistol has a slide cut with four different mounting plates. That way, you can install your optic of choice or use the open sights if you prefer, with the option to install an optic later. If you need a cheaper way to do some defensive training or just need a fun plinker, look no further. Buy your Umarex Gen 5 Glock 17 MOS Half Blowback BB Pistol from Airgun Depot, today.
