Glock 49 Gen 5 MOS OEM Slide

Build or upgrade your Glock 49 Gen 5 with a factory-spec Glock 49 Gen 5 MOS OEM Slide, the optics-ready upper assembly that delivers trusted Glock handling, extended sight radius, and proven durability. This slide accepts every proper Gen 5 component, whether you’re completing a new build or upgrading to a red dot-ready setup.

Product Description | Specs for Glock 49 Gen 5 MOS OEM Slide

Machinists forge the Glock 49 Gen 5 MOS OEM Slide from steel and finish it to withstand everyday carry, recoil forces, and holster wear. Built specifically for the Glock 49 Gen 5 platform, this slide pairs a Glock 17-length slide profile with a compact Glock 19-size frame, giving you a longer sight radius and a more muzzle-heavy feel for better recoil control.

The slide incorporates the correct rail geometry, breech face, and striker channel to mate with a Glock 49 Gen 5 frame, 4.49″ barrel, and compatible upper parts kit without modification.

What’s Included For Complete OEM Slide

A complete OEM Glock 49 Gen 5 MOS slide assembly normally includes:

• Glock 49 Gen 5 MOS slide (machined with optic-ready cut and included cover plate)
• Glock Marksman barrel (9mm Luger, 4.49″ length)
• Glock upper parts kit, including:
  • Striker and striker spring
  • Spring-loaded bearing
  • Firing pin safety and spring
  • Extractor and extractor depressor plunger assembly
  • Slide cover plate
  • Rear sight and front sight (factory sights, model dependent)
  • Recoil spring assembly (dual spring, Gen 5 spec)

What’s Included For Stripped OEM Slide (No UPK)

A stripped OEM slide gives you the bare machined slide only:

• Glock 49 Gen 5 MOS slide only (optic cut, no cover plate installed)
• Machined and ready for upper parts kit installation

Stripped slides exclude internal parts, barrel, sights, and recoil spring components.

How To Disassemble a Glock 49 Gen 5 MOS OEM Slide

1. Remove the slide from the frame and store it separately.
2. Remove the mounted optic (if installed) before storage or shipping.
3. Remove all magazines and store them separately.
4. Run a cable lock or trigger lock through the frame/magwell.

• Magazines: Glock 19 15-round and Glock 17 magazines fit a complete build on this slide/frame combo
• Gen Mix: Don’t mix Gen 5 slide parts with Gen 3 components — verify compatibility before mixing parts from other Glock generations

What’s the Glock 49 Gen 5 MOS OEM Slide Made Of?

Machinists cut the Glock 49 Gen 5 MOS OEM Slide from forged carbon steel for strength and wear resistance, then finish it with a durable nDLC coating that resists corrosion and holster wear. They precision-machine the factory MOS cut to preserve slide integrity and hold a consistent optic zero.

Customization Options

• Slide Serrations: Factory forward and rear serrations aid manipulation; upgrade further if you want more purchase
• Optic Plates: Add MOS mounting plates to run multiple optic footprints
• Sights: Install suppressor-height or night sights that co-witness with your optic

Note: Modifications may affect warranty or serviceability. Consult a qualified armorer.

FAQs

Q: Does this slide include internal parts?
Complete kits include internal components, barrel, and sights; stripped slides don’t. Always verify what’s included before you buy.

Q: Will this slide fit a standard Glock 19 Gen 5 frame?
Yes. The 49 pairs a Glock 17-length slide with a Glock 19-size frame, so it runs on Gen 4 and Gen 5 compact frames, but always confirm fit with your specific components. It won’t interchange with Gen 3 frames.

Q: What optics fit the MOS cut?
Most MOS-footprint red dots fit using the correct adapter plate — always confirm your specific optic’s footprint first.

Q: Will an aftermarket UPK affect performance?
Quality aftermarket kits function well, but OEM-spec parts typically deliver the most consistent reliability.
