Description
The Black & White Cal King Adult Male is a precision-machined slide cover plate designed for Glock 43X and 48 models. It replaces the factory rear plate, providing a clean, two-tone aesthetic while maintaining full sight compatibility. This part is for owners who want to personalize their EDC or competition pistol without sacrificing reliability. We’ve stocked this since early 2024, and it’s become a repeat purchase for customers building multiple setups.
Stand-Out Features
- Two-Tone Finish: Features a durable black nitride finish on the main body with a crisp, machined white “CAL KING” logo for a distinctive look.
- Universal Sight Compatibility: Our staff has confirmed fitment with both factory Glock sights and popular aftermarket options from Trijicon and AmeriGlo.
- Direct OEM Replacement: Machined from 4140 steel to match OEM dimensions. Installs in seconds using the existing rear sight tool and retains the factory sight notch.
- No Function Impact: This is a cosmetic upgrade only. It does not alter slide weight distribution, striker function, or disassembly.
- Minimal Added Weight: Adds a negligible 0.6 ounces to the slide, preserving the pistol’s original balance and handling characteristics.

Your Questions Answered
Does this plate work with optic-cut slides?
No. This plate is designed specifically for slides using the standard Glock rear sight dovetail. It is not compatible with slides that have been milled for a Red Dot Optic (RDO).
Will the white lettering wear off?
The white is not a paint fill; it’s the bare machined metal. The logo is laser-engraved and then the entire piece is finished. The contrast is permanent and will not fade or rub off with holster use or cleaning.
Is the included hardware different from OEM?
No hardware is included. You reuse your factory rear sight and its set screw. The plate itself is the only component. Ensure your sight is properly torqued during re-installation.
