45 ACP / 4.25" Commander Tactical / Anodized Black 1911 Build Kit



Building a top-tier 1911 that competes with the most well-made 1911s on the market sounds too good to be true, but it isn’t. That’s because our 4.25” Commander Tactical Anodized Black 1911 Build Kit includes everything you need to build such a gun at home with basic hand tools. Made from 7075 T6 aluminum, the frame in this kit reduces the 1911’s weight by over 60% when compared to a full-size steel frame. Coupled with the shortened 4.25” Commander profile, this build kit produces a 1911 that’s perfect for all-day carry.
