Glock 48 MOS 9mm 15+1

Glock 48 MOS 9mm 15+1

The Glock 48 MOS 9mm pistol represents Glock’s most capable Slimline carry configuration yet — factory 15-round capacity, optics-ready MOS slide, and an integrated front rail in the slim package that made the G48 a favorite among serious concealed carriers.

Built on Glock’s proven Slimline platform, the G48 MOS delivers the same length and height as the G19 in a dramatically slimmer 1.10-inch wide package. Because the width of a carry pistol determines how much it prints against clothing, the G48’s Slimline frame provides a meaningful concealment advantage over full-size and standard compact platforms without sacrificing barrel length or sight radius. The 4.17-inch GLOCK Marksman Barrel delivers the match-grade accuracy of the Gen5 GMB design, and the nDLC finish provides superior corrosion and scratch resistance across all metal components. Additionally, the Slimline MOS slide cut accepts the Shield RMSc footprint directly — no adapter plates required — keeping the optic as low as possible to the bore axis for a more natural sight picture.

This variant ships factory-direct with two OEM Glock 15-round magazines — a significant upgrade over previous G48 configurations. Furthermore, the integrated GLOCK Slim Mounting Rail allows mounting of tactical lights and accessories without aftermarket frame modifications. The built-in beavertail, reversible magazine catch, short trigger distance, and precision-milled front serrations round out a platform that reflects Glock’s Gen5 engineering standards throughout.

Why the Glock 48 MOS 9mm Pistol Stands Out

The G48 MOS has always occupied a unique position in the Glock lineup — similar dimensions to the G19 but significantly slimmer, which means it conceals more effectively for a wide range of body types and carry positions while still delivering a full 4.17-inch barrel. Because of that combination, it has become one of the most popular optics-ready carry platforms on the market. However, the previous configuration shipped with 10-round magazines, which required an aftermarket purchase to reach meaningful capacity.

This variant changes that entirely. Because Glock now ships the G48 MOS with factory OEM 15-round magazines, the shooter gets full capacity out of the box without relying on third-party solutions. Furthermore, the integrated front rail adds accessory mounting capability that the standard G48 lacked — making this the most complete factory G48 MOS configuration Glock has released. For the carry shooter who wants a slim optics-ready 9mm with factory reliability at every component level, the G48 MOS 15+1 Rail represents the most capable version of an already proven platform.

Technical Specifications

Compatibility Information

Optic Compatibility The Slimline MOS slide cut accepts the Shield RMSc footprint directly — no adapter plates required or included. Because this is a non-standard MOS footprint specific to the Slimline series, standard full-size MOS adapter plates are not compatible. Verify optic footprint before purchase.

Accessory Rail Compatibility The integrated GLOCK Slim Mounting Rail accepts slim-profile tactical lights and lasers designed for the Slimline rail system. Additionally, it is not compatible with standard full-size Picatinny rail accessories — verify compatibility with your specific light or laser before purchase.

Magazine Compatibility Ships with two factory OEM Glock 15-round magazines. Because this magazine is the same OEM unit sold separately, additional magazines are available — see our Glock OEM 15-Round Magazine listing.

Holster Compatibility The G48 MOS with front rail requires holsters specifically designed for the railed G48 MOS configuration. Verify holster compatibility before purchase.
