Introducing SilencerCo's Latest Innovation
SilencerCo has returned to the pistol enhancement arena with an exciting new offering that may appeal to enthusiasts who admire the Maxim 9 but haven't been able to acquire one. While the new SCO Slide won't transform your Glock into an integrally suppressed firearm, its distinctive design draws significant inspiration from SilencerCo's groundbreaking 9mm suppressed pistol. This premium upgrade comes with the added benefit of being pre-cut to directly accommodate your choice of popular pistol red dot sights, eliminating the need for adapter plates.
Design Features and Construction
The SCO Slide for Glock 19 Gen 1-3 pistols represents a significant enhancement opportunity for G19 owners. Available with specialized cuts for RMR, ACRO, and 509T optics, the slide offers versatile sight compatibility to match your preferred aiming solution.
Premium Materials and Finish
Crafted from 17-4 stainless steel known for its superior corrosion resistance, the SCO Slide delivers exceptional durability under various conditions. The premium black diamond-like coating (DLC) further enhances the slide's resistance to both surface wear and corrosion, ensuring longevity through years of use.
Maxim 9-Inspired Aesthetics
One of the standout features of the SCO Slide is its distinctive side serrations, directly inspired by the celebrated Maxim 9 design. These serrations aren't just visually appealing—they provide enhanced grip for slide manipulation, making routine operations like clearing jams or chamber checks remarkably effortless. The slide also incorporates eye-catching side-cutout windows that contribute to its unique visual profile.
Compatibility and Technical Notes
It's important to note that with most variants, cover plates and screws are not included and must be purchased separately. However, the RMR variant does include two mounting screws.
The SCO Slide leverages patented optic cut technology developed by ZEV Technologies (U.S. Patent No. RE47335), ensuring precise fitting and reliable performance.
Value and Practical Benefits
Priced at $299, the SCO Slide provides Glock 19 owners with a straightforward upgrade path to enhance both function and aesthetics. The direct mounting capability for premium red dot sights eliminates adapter plates, resulting in improved co-witness potential and optimal height over bore.
Practical Advantages
The corrosion-resistant construction and DLC coating suggest this slide is built for lifetime durability, while the distinctive Maxim 9-style serrations enhance grip for reliable operation under stress. Beyond functionality, the slide's unique side windows create a contemporary aesthetic that distinguishes it from both factory Glock slides and other aftermarket options.
User-Friendly Installation
For those concerned about installation, SilencerCo's website offers comprehensive guides and detailed compatibility information, making the upgrade process accessible even for those with limited gunsmithing experience.
