At this year's SHOT Show, Glock debuted the G19X-MOS (Modular Optic System), allowing the easy installation of your favorite pistol optic directly to the slide without the need of a gunsmith. Also at SHOT Show, Glock showed off the G49, which gives the shooter the longer sight radius of the popular G17 with the ease of concealed carry offered by the shorter grip found on the G19.
