Build a premium custom Glock® 19 Gen 3 with this precision-machined aftermarket slide designed for improved durability, optic compatibility, and enhanced handling. Made from heat-treated 416 stainless steel, this slide provides a strong and durable foundation for a custom pistol build while offering a premium appearance with its Black DLC (Diamond-Like Carbon) finish.
This slide features a direct RMR footprint optic cut, allowing you to mount popular red dot optics directly to the slide without the need for adapter plates. A direct-mount optic setup provides a lower profile installation, fewer components, and a clean, integrated appearance compared to factory MOS-style systems.
Aggressive front and rear slide serrations provide improved grip during slide manipulation, press checks, and malfunction clearance. The additional front slide cutout/indentation provides enhanced purchase when manipulating the slide while adding a distinctive custom look.
Whether you’re building a concealed carry pistol, training handgun, competition setup, or simply upgrading your Glock 19, this slide combines premium materials, modern features, and a refined finish for a high-performance custom build.
Internal components and barrels sold separately, you can also have us assemble and test fire the slide prior to shipment, that’s an option.
Premium 416 Stainless Steel Construction
This Glock 19 Gen 3 slide is machined from 416 stainless steel, a popular material choice for firearm components due to its excellent strength, corrosion resistance, and ability to achieve precise machining tolerances.
The slide is also heat treated to improve durability and wear resistance, making it well suited for daily carry, training, and high-round-count use.
Black DLC Finish – DLC vs Cerakote
The Black DLC finish provides a premium upgrade over traditional firearm coatings. DLC (Diamond-Like Carbon) is a hardened PVD coating known for its excellent wear resistance, low friction, and smooth finish.
Advantages of DLC:
- Extremely durable surface coating
- Excellent resistance to scratches and abrasion
- Smooth, low-friction surface
- Excellent corrosion resistance
- Premium deep black appearance
DLC vs Cerakote
Cerakote remains a popular firearm finish because of its wide range of colors and customization options, including popular finishes like FDE, OD Green, Tungsten, and Burnt Bronze. It provides excellent corrosion protection and a quality firearm-specific coating.
DLC is typically chosen by shooters looking for a more performance-oriented finish due to its increased hardness, slick surface, and resistance to wear from holsters and repeated use.
Both finishes are excellent options depending on your goals:
- Choose DLC for maximum durability and a premium hard-use finish
- Choose Cerakote for color customization and unique builds
Direct RMR Cut vs Glock MOS
This slide uses a direct Trijicon RMR footprint optic cut, allowing compatible optics to mount directly to the slide.
Compared to the Glock MOS system, a direct-milled optic cut offers several advantages:
- Lower optic mounting height
- Fewer parts between the optic and slide
- Improved rigidity
- Cleaner appearance
- More streamlined installation
The RMR footprint is one of the most widely supported pistol optic footprints available and works with many popular red dot optics.

This slide is compatible with optics using the Trijicon RMR footprint, including:
- Trijicon RMR
- Trijicon SRO
- Holosun 407C
- Holosun 507C
- Holosun 508T
- Holosun 507Comp
- Other optics utilizing the RMR footprint

Sight Installation Notice
If using a sight pusher tool to install sights, use a tool that properly supports the entire side of the slide. Avoid sight pushers that only contact a small portion of the slide rail, as concentrated pressure can potentially damage or deform the slide.
Improper installation methods or the use of incompatible tools may result in damage to the slide, sights, finish, or optic cut area. Damage caused during installation is not covered under warranty.

sound of freedom – This was a great set up. I loved being able to customize the set up. Only issue I had was my own fault as a newb to building these. I used a heavy barrel in a slim hand guard. It makes adding attachments tough with clearances. Hoping someday to also get an AR10 from here.
