Nitride Finish and Durability

The black nitride finish on both the slide and barrel sets this platform apart from standard blued or parkerized alternatives. Nitride treatment hardens the steel surface and creates a protective layer that resists corrosion, salt spray, and moisture exposure. This finish maintains its appearance through regular use and requires minimal maintenance compared to traditional finishes.

RMSc Optic Compatibility

The slide is cut for RMS footprint optics with an installed cover plate. This window cut allows mounting of modern compact red dot sights without requiring additional adapters or modifications. The optic cut is milled during manufacturing, ensuring precise alignment and repeatability for your chosen sight system.

Compact Magazine Platform

The 15-round PSA Dagger Micro magazine uses a micro slick finish and is compatible with G43X and G48 platforms. This capacity balances magazine size with firepower in a compact form factor. The polymer magazine catch remains standard, ensuring reliable feeding and retention.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify optic compatibility before mounting. Lower receiver not included.
