About Glock Pistol

Glock 17 gen 5 with trijicon SRO

The Glock is a series of polymer-framed, short recoil-operated, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock Ges.m.b.H.

It is a top performer in reliability, simplicity and safety. The most popular models are the G17, G34 and G19 in 9mm.

The recent MOS, gen 4 and gen 5 models are upgraded with many optimized tweaks, and the ability to mount a red dot for better aiming.

Glock is now pretty much everywhere and is widely considered to be “America’s handgun".
