When scores of law enforcement officers, gun enthusiasts and elite military units consider Glock to be an essential and “bulletproof” tool of the trade, you know you’re talking about a platform people stake their lives upon.

While 2015 brought us Glock’s Modular Optics System, added to G34, G35 and other long-slide models, the technology was not available on what appears to be their most popular guns, the G17 Gen4 and G19 Gen4, until now.

In 2016, MOS versions of the Glock 17 and 19 capitalize on last year’s highly effective competition and hunting technology, and deliver it to other areas of interest, including law enforcement, civilian personal defense and just good ol’ handgun lovers. In the case of G17 and G19 Gen4 MOS competition, these specific models are also great for USPSA, IDPA and other semi-auto pistol contests.

For time and length’s sake, let’s take a look at the Glock 19 Gen4 MOS.

The Glock 19 9mm has long been revered as a premier 9mm handgun and is certainly one of Glock’s most popular offerings. Not much has changed in basic parts and operation. G19 Gen4 still features Glock’s popular, rock-solid polymer lower/ steel slide configuration, comfortable Gen4 textured technology and a modular backstrap for a more customized fit. The Glock 19’s SAFE ACTION, 4.02 inch steel barrel, 7.28 inch overall length and 23.63 ounce empty weight, along with a dual-recoil spring and reversible magazine catch, delivers the kind of non-stop performance, reliability, balance and durability that has made Glock arguably the most popular handgun brand in the industry.

The double-stack platform accommodates up to 15+1 rounds of 9×19-cal.

The addition of a red dot sight might take some getting used to for our legion of old-school fixed sight gun owners; however, there’s no arguing the simplicity of red-dot optics, especially when things get ugly or competition heats up. The Glock 19 Gen4 MOS is quickly catching the eyes of competitors, law enforcement and armed citizens alike for personal defense, sporting and even hunting.
