Whether you love customizing your weapons from the ground up or you're a first-time owner ready to exercise your Second Amendment rights, these 80 percent handgun parts kits provide most tools required for assembling a completed 80% pistol frame (sold separately, fabrication required) into a truly reliable, accurate pistol. These handgun parts are designed by experienced arms makers and use only components made in the U.S.

These 80% parts are available for the following makes and models:

  • 1911 Government (.45, 9mm)

Pistol Parts Kits: What's Included

Our pistol parts kits include all the components required to assemble your fabricated 80% frame, minus a magazine. Of course, customizing a pistol from scratch is one reason why many owners choose to build their pistols in the first place. Check out our custom GLOCK slides, frame parts kits, and upgraded barrels.

State Laws Vary

Some states have restricted handgun parts and kits, like those available here. States like California require that you undergo a background check and serialize your handgun before you build it. Other states have banned 80% handguns and build kits altogether.

Please read our Shipping & Return Policy to determine if we can ship to your state. Orders placed by residents in restricted states cannot be fulfilled and will be canceled, less any restocking fees.

 Now get started! Your custom handgun build awaits.
