The original GLOCK 19 is a popular concealed-carry pistol due to its compact dimensions. Gen5 features and the Modular Optic System (MOS) also give this CO₂-operated airgun ideal qualities for sports and recreational shooting.

When shooting with 4.5 mm (.177) steel BBs, the metal slide of the GLOCK 19 Gen5 MOS is particularly impressive. In addition to a powerful blowback, it is equipped with an integrated recess for point sights. The included adapter plates allow the mounting of point sights with Trijicon, Docter, Leupold and C-More footprints, which greatly simplify aiming compared to iron sights. A cover plate is mounted by default for the use of the standard sights.

The superior shooting experience is further enhanced by typical Gen5 features such as the additional front serrations and the ergonomic grip with a reversible magazine catch and ambidextrous slide catch lever. This airgun can also be field-stripped just like the original. An automatic trigger safety prevents accidental firing, and the extended magazine bottom plate also serves as a grip extension. This model is compatible with aftermarket holsters.
