For concealed carry and everyday defense, a balance of slim profile, controllability, and accuracy matters more than raw size. The right pistol should disappear on the draw while delivering confident hits when it counts.

GLOCK G48 MOS is chambered in 9×19 and combines the Slimline platform with the Modular Optic System to offer a near-perfect blend of concealability and capability. The G48 MOS features the GLOCK Slim Mounting Rail for tactical accessories, short trigger distance, a frame with a built-in beavertail, reversible magazine catch, and the match-grade GLOCK Marksman Barrel (GMB) from the Gen5 series. The slim magazine includes an orange follower for higher visibility and holds 10 rounds; note the MOS does not include adapter plates.

Key features and how they perform

The 9×19 chambering is the industry standard for defensive pistols: widely available, offering manageable recoil, and proven terminal performance when paired with quality defensive ammunition. The GMB Gen5 barrel elevates accuracy across the defensive shooting spectrum, from close-quarters engagements to controlled precision at typical defensive distances.

Slimline ergonomics and controls

Short trigger distance and a built-in beavertail give consistent reach and positive hand placement for shooters of varied hand sizes. The reversible magazine catch supports left- or right-handed manipulation, and the slim magazine profile maintains a low concealment footprint while providing the mandated 10-round capacity with an orange follower for easy visual confirmation of magazine status.

Accessory-ready with MOS and rail

The GLOCK Slim Mounting Rail lets you add lights or lasers without adding bulk. The MOS allows mounting reflex optics to the slide, but remember adapter plates are not included with the pistol — plan to obtain the proper plate for your chosen optic. Precision-milled front serrations aid press checks and slide manipulation under stress.

At a listed price of $508.99, the GLOCK G48 MOS positions itself as a tactical, duty-grade option in a highly concealable package. For specifications and to make a purchase, View product details and pricing.
