The Glock G19 Gen 5 MOS enhances the already exceptional Gen 5 model with the Modular Optic System (MOS), making it even more desirable. Its precision-machined slide offers a seamless mounting platform for popular optic sights, supported by multiple adapter plates for easy installation of miniature electronic sights at the rear. Featuring front serrations for enhanced handling, this compact-size pistol retains all the hallmark Gen 5 qualities: the latest Glock nDLC surface finish known for its superior hardness and rust resistance, a high-traction Gen 5 frame texture, a reversible magazine catch for swift adjustments, an ambidextrous slide stop lever and the versatile Glock Modular Backstrap System (MBS) for personalized operator comfort. Combined with the universally-praised Glock Safe Action System and high-visibility orange magazine followers, it exemplifies Glock's commitment to performance and innovation.
