The GLOCK G19 is probably the most ubiquitous pistol on the planet, and for good reason. The pistol is a perfect "in-between size"; its compact size makes suitable for conceal carry, while its robust capacity, extremely flat recoil impulse (thanks to GLOCK's low bore axis), and accessory rail makes it a great choice for home defense and duty applications. With an abundance of aftermarket and OEM accessories on the market, the GLOCK G19 is the perfect pistol for new and experienced shooters alike. The GLOCK Modular Optic System (MOS) further extends the capabilities of the G19 by allowing the user to mount a red dot optic to the slide through the usage of included mounting plates.
