Glock Introduces Modular Optic System (MOS) Pistols

Glock Introduces Modular Optic System (MOS) Pistols

Until the 2015 SHOT Show, equipping a Glock pistol with a mini red dot sight (MRDS) required custom gunsmithing that was often expensive and risked voiding the pistol's factory warranty.

Now available as an OEM offering, Glock's new Modular Optic System (MOS) configuration makes it easier than ever to mount common MRDS optics such as the Trijicon RMR and Leopold DeltaPoint. Glock's MOS configuration will be initially offered on four pistols:

- 9mm G34


- .40 S&W G35


- .45 ACP G41

- NEW 10mm G40 pistol

With a 6-inch barrel and 15-round magazine, the 10mm G40 reflects the largest handgun ever produced by Glock. The G40 looks to be a great option for hog hunting or as a sidearm in bear country.

We expect to see additional Glock models equipped with the MOS platform in the future, but for now it is only available on their longslide models.

Shooting 600 Yards with .300 Blackout

Shooting 600 Yards with .300 Blackout

The .300 Blackout cartridge was developed to provide greater effectiveness than a 9mm at short and medium ranges when fired from a short-barreled suppressed firearm. Just because the cartridge wasn't designed to go long doesn't mean Rifles & Optics Editor Tom Beckstrand won't take it there, using a large-format pistol, no less. Armed with SIG Sauer's 9-inch-barreled MCX Virtus Pistol loaded with Black Hills' 125-grain TMK ammunition, Beckstrand attempts to ring steel at 600 yards with help from Hornady's 4DOF ballistic calculator in this segment of “Long Range Tech.”

Pocket-Pistol Carry Tips and Tricks

Pocket carry, as a method of concealed carry for a defensive firearm, can be a practical option when done right. This is especially true during the colder months when heavy outer garments can obstruct access to a traditional waistline holster. Former U.S. Navy SEAL Jeff Gonzales, president of Trident Concepts, joins G&A contributor Kimberly Heath-Chudwin to discuss guns, training and gear, including Blackhawk's TecGrip holster that can make pocket carry more successful.

In this segment of “Pros vs. Joes,” we put competitive shooter and author James Tarr against Guns & Ammo TV cameraman Nathan Wilt. With handguns, they see who can knock down plates the fastest on two Revolution Targets Heavy Duty Plate Racks. Here's the catch: Tarr has to use a Colt King Cobra in .357 Mag. while Wilt shoots a Smith & Wesson M&P9 M2.0 in 9mm.
