Las Vegas, Nev. – Jan. 18, 2016  Today, GLOCK, Inc., announced the release of two new pistols to join the Modular Optic System (MOS) series, the G17 Gen4 in MOS and the G19 Gen4 in MOS.

Now, two of GLOCK’s best selling pistols are available with milled slides designed specifically to be adaptable to multiple optic systems without costly customization. The G17 Gen4 MOS and G19 Gen4 MOS are the ideal addition to the series as the market continues to trend toward optic-ready everyday carry and defense.

“We’re seeing more and more professional trainers recommend the use of optics for primary and defensive use,” stated Josh Dorsey, vice president at GLOCK. “Optic ready pistols will enable faster target acquisition when a reflex sight is mounted.”

Both pistols are chambered in .9mm and do not differ in specifications from their respective standard models. Other MOS pistols, introduced in January of 2015, are the G34 Gen4 MOS, G35 Gen4 MOS, G41 Gen4 MOS, and the G40 Gen4 MOS. The new models were unveiled today at the Range Day for SHOT Show and will be on display at the GLOCK booth (#12254) throughout the week. The pistols will be available for purchase at retailers in the following weeks.

Last year at Range Day, we were able to shoot the G34 Gen4 in 9mm MOS.  The G17 and 19 MOS add the standard and compact sizes to the 9mm optics family.  The other pistols already in the line are full-sized guns in .40 S&W cal. and .45 ACP.  If you find yourself needing an optic, here ya go!
