About this product
What is the Glock 48 Gen5 MOS 9mm 4.17″ 10rd 2 Mags? It's a striker-fired, polymer-framed compact pistol purpose-built for concealed carry and duty use, featuring a 4.17-inch Match Grade Glock Marksman Barrel and a Modular Optic System slide cut ready for micro red dots. This model represents Glock's evolution of the slimline platform into the MOS ecosystem, maintaining the 10-round single-stack magazine capacity while adding modern mounting capability. At 7.28 inches overall length, it bridges the gap between full-size service pistols and ultra-compact subcompacts.
What is the Glock 48 Gen5 MOS used for?
The Glock 48 Gen5 MOS is engineered specifically for concealed carry duty, law enforcement backup, and personal defense applications where a minimal profile is paramount. Its 1.0-inch width at the slide and 1.1-inch grip circumference make it 28% thinner than standard double-stack Glocks like the G19, allowing for deeper concealment without sacrificing a full firing grip. The MOS optic cut accommodates popular micro red dots including the Holosun 507K and Shield RMSc, enabling faster target acquisition than traditional iron sights alone when milliseconds matter.
How does the Glock 48 Gen5 MOS compare to the Sig Sauer P365 XL Spectre Comp?
The Glock 48 Gen5 MOS offers superior aftermarket support and simpler manual of arms compared to the Sig Sauer P365 XL Spectre Comp, while the Sig provides higher capacity in a similar footprint. The Glock's 10-round single-stack magazines create a grip that's 0.3 inches thinner than the Sig's 12-round flush fit magazine, a noticeable difference when carrying appendix position for 8+ hours daily. Where the Sig excels with its integrated compensator reducing muzzle flip by approximately 15%, the Glock maintains the mechanical simplicity that's proven across millions of duty hours—a trade-off between maximum performance and absolute reliability.
What does it weigh and what are the dimensions?
The Glock 48 Gen5 MOS weighs 20.74 ounces unloaded and measures 7.28 inches in total length with a 4.17-inch barrel and 5.04-inch height including magazine. The slide width at the mounting plate measures exactly 0.87 inches, while the grip circumference at its thickest point is 5.47 inches around—compare this to the Stevens 334's 1.5-inch wide receiver to understand why this pistol disappears under clothing. Loaded with 10 rounds of Federal 124-grain HST, total carry weight increases to approximately 25.9 ounces including a Trijicon RMRcc optic.
Who is this NOT for?
This pistol is not suitable for competition shooters needing extended magazine capacity or home defense primary users prioritizing maximum round count. While the 10-round limit complies with restrictive state regulations, it represents a 33% capacity reduction compared to the Glock 19's 15-round standard magazines. Duty officers requiring weapon-mounted lights should note the front accessory rail accepts only compact options like the TLR-7 Sub, not full-size units like the 800-lumen SureFire X300U commonly issued with service pistols.
What's in the box?
Factory packaging includes two 10-round magazines, four MOS adapter plates (for RMRcc, Holosun K, Shield, and Docter footprints), a cleaning rod and brush, cable lock, and owner's manual. The MOS plates require Torx T10 mounting hardware not included—a deliberate omission that pushes users toward proper gunsmith installation rather than DIY stripping of 12 in-lb torque specifications. Unlike aftermarket kits, no magazine loader or additional backstraps ship with this configuration, though the Stevens 555 Sporting includes both choke tubes and a hard case at similar price points.
Is the Glock 48 Gen5 MOS worth it at $507.99?
At $507.99, the Glock 48 Gen5 MOS justifies its price through factory optic mounting capability not requiring third-party slide machining. Adding MOS compatibility to a standard G48 would cost $180-250 through milling services plus 4-6 weeks turnaround, making this configuration effectively a $300 premium over the non-MOS version for immediate mounting readiness. For shooters transitioning from iron sights to red dot systems, this represents the most cost-effective entry into optics-ready carry pistols from a manufacturer with documented reliability across law enforcement adoptions.

Frequently asked questions
- Is it compatible with Trijicon RMRcc?
- Yes, using included MOS adapter plate #02, though mounting requires purchasing separate Trijicon sealing plate and Torx screws. Proper installation needs 12-15 in-lbs torque on the four mounting screws—exceeding this can crack the optic housing. The MOS system accommodates the RMRcc's RMSc footprint directly without modification.
- Does this fit Glock 43X magazines?
- No, the G48 uses single-stack 10-round magazines with different feed lip geometry than the 43X's hybrid design. Attempting interchange can cause failures to feed at round 8-9 due to different follower angles. Both models share identical frame dimensions but require their respective factory magazines for reliable function.
- How long does shipping take?
- Fully compliant shipments process within 3 business days for FFL verification, then 2-5 days transit via FedEx. California, New York, and Massachusetts orders require additional 24-hour regulatory review for magazine compliance. All shipments require signature confirmation at your selected FFL—no exceptions for Title I firearms under Ironclad Armory policy.
- Can I return it if it doesn't fit my hand?
- No, firearms are non-returnable once transferred through an FFL due to federal serialization requirements. We recommend handling a display model at a local dealer before purchase—the grip circumference measures 5.47 inches, compared to 5.8 inches on double-stack compacts. Custom stippling services can increase grip diameter by 0.1-0.2 inches if needed.
- Does this work with Streamlight TLR-6?
- Yes, the Streamlight TLR-6 for Glock 48 installs directly to the trigger guard without modification. Output measures 100 lumens for 1 hour runtime—sufficient for identification at 7-10 yards but not for tactical search. The integrated laser adds 0.3 ounces to the 20.74-ounce base weight.
