Glock G19X MOS 9mm 19rd Pistol

The G19X MOS is a Glock 9mm that comes with a 19 round magazine. Nineteen rounds is a full size magazine count, so range sessions run longer between reloads and a drill can be finished without a lot of magazine changes. The MOS designation on the slide is Glock's factory optic mounting arrangement, which means a compatible red dot goes on without sending the slide out to a machinist.

Glock pistols are striker fired. There is no external hammer and no decocker to learn, and every trigger press feels the same from the first round to the last. That consistency is a large part of why the platform gets used so widely for training and duty work, and it shortens the learning curve for anyone moving between handguns. Glock magazines, holsters and parts are common enough that setting one up rarely means hunting for hard to find pieces, which keeps a pistol like this easy to live with over time.
