The GLOCK G41 Gen4 MOS is the long-slide competition and duty .45 ACP in the GLOCK lineup. Its 5.31-inch barrel and extended slide give a longer sight radius and a slower, more controllable slide cycle than the standard G21, which translates directly into flatter shooting and faster splits with a full-power cartridge. The slide is lightened to keep the balance neutral despite the added length.

MOS — Modular Optic System — means the slide is cut from the factory to accept a red dot via adapter plates. A serious choice for USPSA Limited shooters and .45 devotees.
