The affordable way to build an optic-ready .45 ACP pistol.
This Glock® 21-compatible build kit provides quality, OEM-grade components for the included slide and your frame, coupled with a precision-milled, heat-treated and Cerakote black slide that's ready for a pistol red dot.
The included slide slide features an RMR optic cut, allowing you to install any of the most popular red dots on the market. Its improved, dynamic front and rear serrations provide extra grip, while its matte black Cerakote and stainless construction make it practically impervious to corrosion and wear. Selection one of two barrel options -- nitride-treated or bare stainless -- and enjoy improved accuracy out of the box.
Pair this build kit with your stripped G21 frame to complete your custom pistol build.
