New MOS Glocks

It has become an international obsession as each year moves on. What will GLOCK be doing next? It is the center of countless discussions online and in person, as well as fuel for numerous blogs. As 2016 began, expectations were high, and GLOCK has hit another home run. New this year are two guns that have been on many people’s wish lists.

Glock 17 Gen4 MOS

GLOCK has expanded its Modular Optic System (MOS) line to now include the iconic GLOCK 17 Gen4. The MOS Configuration makes it easy to mount a miniature reflex sight on the pistol’s slide without having to get a new slide or separate mounting system.

In many people’s minds, it was the G17 that really started GLOCK down this path. Over the years, custom shops have altered countless GLOCK 17 slides to allow for popular reflex sights, or people used out-of-the-box versions that utilized the rear site channel. GLOCK has now taken the lead and is providing its customers the opportunity to get their classic and reliable G17 in the much sought-after MOS Configuration. While it may be hard to believe, the reliable GLOCK 17 Gen4 just got better.

Glock 19 Gen4 MOS

To many, the release of the new G17 Gen4 MOS is seen as a major development. But GLOCK did not stop there. In concert with the new G17 Gen4 MOS, GLOCK has also released the G19 Gen4 MOS. This move shines a light on the growing trend of mounting quick-targeting reflex sights on defensive pistols. Once the exclusive realm of the competition world, reflex sights have made their way onto defensive carry guns. Now available with GLOCK’s popular MOS Configuration, the G19 Gen4 pistol can now easily be fitted for a variety of optics.

The benefits of having a miniature reflex sight on a gun as reliable and accurate as the G19 Gen4 MOS are numerous. First and foremost is the shooter’s ability to acquire and engage targets at high speed. There is no need to close one eye, which improves your overall vision of the events at hand. This takes one of the most relied-upon pistols in the world and takes it to the next level of accuracy and effectiveness. The GLOCK 19 Gen4 MOS will surely lead the industry and become a popular defensive handgun among shooters.

9×19 Glocks

Worldwide, 9x19s are the most popular GLOCKs. The narrow cartridge diameter allows for the maximum cartridge capacity in pistols of a given size. Its recoil is also the mildest of service pistol calibers, promoting ease of learning and fast, accurate hits. The 9×19 is available in a wide variety of loads; a standard-pressure, 147-grain bullet at 990 feet per second (fps) generates about 320 foot-pounds of energy (fpe), while 115-grain +P+ rounds at 1,300 fps deliver 432 fpe.

  • Adequate power with a maximized round count for the gun’s size.
  • Soft recoil for easy controllability and a high rate of accurate, rapid fire.
  • A wide variety of 9×19 ammunition is available.
  • At current ammo prices, the 9×19 is the most cost-effective chambering available.

GLOCK has proven itself as a source for the ultimate in self-defense firearms. From full-sized powerhouses like the G17 to deep-cover compacts like the G26, GLOCK provides shooters with a wide range of options for their personal carry needs. And for those who wanted the smallest GLOCK possible, the company responded with the popular G42 in .380 AUTO. But what about those who wanted a similarly sized pistol, but in the more potent 9×19 cartridge? Well, GLOCK had an answer for that as well.

With the introduction of the GLOCK 43 in 9×19, self-defense enthusiasts have another option for their tactical toolkit. Unlike its G26 sibling with its double-column magazine, the ultra-slim G43 features a six-round, single-column magazine for the ultimate in concealable, 9×19 power.

And, its light unloaded weight of just under 18 ounces will ensure that you will carry it with you wherever you go.

But fans of GLOCK’s renowned combination of simplicity and reliability should fear not. The G43 packs in all the features you have come to love about GLOCK’s pistols. From its foolproof SAFE ACTION system to its multiple safety features to its rock-solid reliability, this is a pocket pistol that you know you can count upon when the chips are down.
