9mm / 4.25" Commander Anodized Black Slide 1911 Parts Kit

Our 4.25” commander Anodized Black 1911 Parts Kit is one of the two halves you need to make that happen. This kit features components made in the USA exclusively from mil-spec 7075 aluminum or Chromoly steel. All you need to do is pair this kit with one of our aluminum 1911 frames from Stealth Arms. The result is a gun with greater carrying capacity (thanks to its 9mm chamber) and a weight reduction of over 60% compared to the original, full-size, steel 1911.
