The Gen4 MOS G-19 comes with a milled slide ready for a reflex sight.
Glock has 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 company says 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.
