Glock 19 Gen 5 Mos

The Glock 20, introduced in 1991, was developed for the then-growing law enforcement and security forces market for the 10mm Auto. The pistol handles both full-power and reduced “FBI” loads that have reduced muzzle velocity. Due to the longer cartridge and higher pressures, the pistol is slightly larger than the Glock 17, having a roughly 2.5 mm (0.1 in) greater width and 7 mm (0.3 in) greater length. Though many small parts interchange with the Glock 17, with a close to 50% parts commonality, the major assemblies are scaled-up and do not interchange. The standard magazine capacity of the Glock 20 is 15 rounds. In 2009, Glock announced they would offer a 152 mm (6.0 in) barrel as a drop-in option

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 black color the Glock usually comes in. The frame includes a lanyard loop and a front lip in the magazine which purpose is to make changing magazines with gloves on easier, but this means the new Gen 5 17-round magazines cannot be used in the Glock 19X because the front lip will block the extended magazine floor plates from locking into the 19X’s magazine well. This can be remedied by switching to a Gen 4–style magazine floor plate  or with a factory +2 extension. The 19X comes with one 17 round magazine and two 19 round magazines, all in coyote color. The Glock 19X has proven to be one of Glock’s best selling pistols, with over 100,000 sold within 6 months of the 19X first being released
