Description
The Glock 48 MOS is a slimline 9mm pistol from Glock's Slimline series that pairs a G19-equivalent barrel length with a single-stack slim frame and factory-integrated Modular Optic System (MOS) and accessory rail — delivering the ideal balance of concealability, shootability, and tactical readiness for everyday carry.	The Glock 49 Gen 6 is a crossover 9mm pistol that combines the longer G17-length slide and 4.49-inch barrel with the compact G19-length grip, delivering 15-round capacity and extended sight radius in a more concealable package — now featuring all Gen 6 enhancements including the Optic Ready System (ORS), flat-face trigger, RTF6 grip texture, and enlarged beavertail. Currently available for international markets.

Pros
Exceptional concealability — G19-length but only 1.1 inches wide for all-day IWB carry Factory MOS optics cut for direct micro red dot mounting without custom milling Integrated Slim Rail for attaching compact weapon lights and lasers Glock Marksman Barrel (GMB) delivers Gen5-level accuracy in a slim profile Built-in beavertail for a high, secure grip and better recoil management Durable nDLC finish provides superior corrosion and scratch resistance Longer 4.17-inch barrel offers better sight radius and more muzzle velocity than the G43X Compatible with Shield Arms S15 magazines for 15-round capacity upgrade Proven Glock reliability — runs virtually any 9mm ammo without failure Extensive aftermarket ecosystem for triggers, sights, lights, and holsters	Crossover design delivers G17 barrel length and sight radius with G19 grip concealability and 15-round capacity Gen 6 ORS optic system mounts red dots lower than previous MOS plates for better dot-to-eye alignment Three optics plates included in box (RMR, DeltaPoint Pro/Shield/Holosun K, C-More) — optics-ready out of the box RTF6 grip texture covers more surface area including thumb rests for superior grip in wet or dirty conditions Gen 6 flat-face trigger offers slightly shorter trigger reach and improved leverage over previous generations Enlarged beavertail enables a higher, more secure grip and reduces slide bite Palm swells and undercut trigger guard improve fit for a wide range of hand sizes Ambidextrous gas pedal thumb rests aid recoil management — previously required aftermarket installation Durable nDLC finish for excellent corrosion and scratch resistance Compatible with most Gen 5 holsters and all legacy G19 9mm magazines
Cons
Standard 10-round single-stack capacity; requires aftermarket Shield Arms mags for competitive capacity MOS cut limited to Shield RMSc footprint; larger RMR-sized dots require slide milling or adapter plates Non-standard rail width — requires MOS-specific holsters; incompatible with standard G48 holsters More recoil and muzzle flip than the G19 due to lighter, slimmer frame Factory sights are basic plastic; most users upgrade to night sights or fiber optics Optics adapter plates not included in the box — must be purchased separately	Currently available for international markets only — U.S. availability not confirmed at launch G17-length slide makes it larger and slightly harder to conceal IWB than a standard G19 Gen 6 frame uses new proprietary parts — not fully backward compatible with Gen 1–4 internals Standard factory sights are basic; most users will upgrade to night sights or a red dot ORS direct-mount footprints limited to RMR, DeltaPoint Pro/Holosun K, and C-More at launch — other optics may need adapter plates Gen 5 Kydex holsters may need retention adjustment due to new enlarged slide stop and integrated beavertail
