The 19X is the civilian version of Glock's entry to the XM17 Modular Handgun System competition for the US Military. It features a Glock 19 slide with a Glock 17 frame in coyote color instead of the regular Glock black color. The frame includes a lanyard loop, underbarrel picatinny rail, and a front lip in the mag for easier magazine changing with gloves. Only downside is no Gen 5 mags can be accepted.
