Glock engineers have developed the Glock Modular Optic System to simplify mounting of popular optic sights without costly custom machining of the pistol’s slide. Optical sights are popular in competitive shooting and are becoming increasingly popular for concealed carry, home defense and target shooters.
The GLOCK 19 Gen4 MOS, in 9x19, introduces revolutionary design changes to the pistol that has found worldwide acclaim with security services both private and public. The Modular Back Strap design lets you instantly customize its grip to adapt to an individual shooter’s hand size. The surface of the frame employs the new scientifically designed, real-world-tested, Gen4 rough textured technology. Internally, the new GLOCK dual recoil spring assembly substantially increases the life of the system. A reversible enlarged magazine catch, changeable in seconds, accommodates left or right-handed operators. The G19 Gen4 9x19mm retains the GLOCK accessory rail for your attachments.
Each pistol is delivered only after passing stringent quality inspections, exhaustive quality control checks, and test firing.
Your new GLOCK pistol is delivered as a complete set. The hard shell case which houses your pistol also includes a speed loader, three magazines, two backstraps, a cleaning set, a MBS tool, a cable lock and instruction manual.
This is my first Glock. I own a few other pistols, but this Glock 19 Gen 4 has now become my everyday carry handgun. Right out of the box, I shot the first 200 rounds of 115 grain ball ammo, and 124 grain JHP, this gun performed flawlessly as I expected from a Glock! I like the fact that I can easily mount a red dot optic with the adapter kit that comes in the case with the handgun. Shipping took about four days, which isn't bad during a pandemic. Overall I'm satisfied with my purchase and the customer service from Sportsmans Outdoor Superstore. I'm looking forward to my next purchase in the near future!
