What the Glock 48 MOS OEM Slide Is Made Of

Glock builds the 48 MOS slide from hardened, high-strength steel engineered to last through thousands of rounds. The factory nDLC (nitride) finish resists wear, cuts friction, and fights corrosion. Glock inspects every component to meet OEM quality standards for durability and consistent performance.

Note: Permanent slide modifications can affect factory warranty and safety. Always use a qualified professional for advanced work.

FAQs

Q: Is this slide ready to fire out of the box?
The slide ships fully assembled with barrel and internals but needs a Glock 48 MOS-compatible frame and magazine to function.

Q: Is it optic-ready?
 Yes. The Glock 48 MOS slide features a Modular Optic System cut for easy optic mounting. Optic plates and red-dots sell separately.

Q: Can I use it on a standard Glock 48 frame?
It fits most Glock 48 frames. To use optics properly, pair it with an MOS frame or confirm compatibility before purchase.

Q: Does it include sights?
Yes. It ships with factory-installed dovetail sights. You can replace them with night sights or remove them to mount an optic.

Q: Do I need a gunsmith for installation?
Most users install it as a drop-in replacement following Glock’s instructions. For optic mounting or sight zeroing, consult a professional.

Q: Is the nDLC finish durable?
Yes. The nDLC (nitride) finish increases surface hardness, lowers friction, and provides strong corrosion resistance.
