The announcement of the Glock 45—a new 9mm G19X-inspired model with a black Glock nDLC finish and front slide serrations—was big news yesterday, but the Smyrna, Ga.-based company also just dropped two other pistols: the Glock 17 Gen5 MOS and Glock 19 Gen5 MOS.

Like the Glock 45, these new pistols also sport front serrations. In addition, the G34 Gen5 MOS, first introduced in January, is available with those same serrations. There’s no word yet on the MSRP for these models. Look for these to be available beginning on Oct. 5. Read the full press release below for additional details.

Glock 17 & 19 Gen5 MOS

GLOCK, Inc.,. expands the 5th Generation of GLOCK pistols with the addition of two modular optic ready platforms. The GLOCK 17 Gen5 MOS and GLOCK 19 Gen5 MOS come optic ready right from the factory and enable users to mount their preferred reflex sights to their pistol in order to improve their target acquisition.

The G17 Gen5 MOS and G19 Gen5 MOS complete the evolution of perfection for the 9X19 family of Gen5 pistols

“The MOS platform offers a convenient way for users to mount reflex sights without costly alterations to an original GLOCK slide,” said GLOCK, Inc. VP Josh Dorsey. “The resulting combination of optical sighting and the unparalleled accuracy and reliability of the new generation of GLOCK pistols set a new standard for this class of pistol.”

These Gen5 models are precision-machined to provide a mounting system for all popular optic sights. With multiple adapter plates, you can quickly and easily mount electronic sights to the rear of the slide. The Gen5 MOS family of pistols also feature front serrations for easier and quicker manipulations. This includes the addition of front serrations on the G34 Gen5 MOS which was first introduced to the market in January, 2018.

The G17 Gen5 MOS and the G19 Gen5 MOS will be available for purchase starting October 5th, 2018 at participating dealers. For additional information about GLOCK Modular Optic ready pistols, visit
