80 Pistol Frames
An affordable way to own a Glock® -Compatible or 1911 pistol, without having to pay extra at the gun shop.
80% pistol frames like these allow you to properly build, customize, and configure a Glock®-compatible handgun or quality 1911 in .45 ACP or 9mm, with no gunsmithing experience or special tools required. Once fabricated at home, your finished Polymer80 80% frame will be capable of accepting any Gen3 Glock® components, or your completed 1911 frame will be capable of receiving any factory or aftermarket 1911 parts in the appropriate caliber and size (Government or Commander, depending on your selection).
What is an 80% pistol frame?
An 80% frame is an unfinished firearm that is not considered a gun under federal law (to learn more, read this guide: "What is an 80% Lower?"). Since the frame is not fabricated and cannot accept a barrel, trigger, or other parts, the ATF considers them legal and does not regulate the frame as a firearm. That means you can purchase an 80% frame without needing to visit an FFL, conduct a background check, or pay dealer fees.
State Laws May Vary
Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
Advantages of Using an 80% Frame
You may think buying a fabricated frame at an FFL or gun dealer would be the easiest route for building a custom 1911 or Glock®. But cutting and drilling a an unfinished frame provides some advantages:
- More affordable. You're not paying dealer or transfer fees, extra taxes, or marked up retail prices when you use an 80% frame for your pistol build.
- Ships direct. Since 80% frames aren't firearms, they can be purchased and shipped like any other gun part. Some states have certain restrictions or have banned these types of parts. Check our Shipping & Return Policy before ordering to verify your state isn't restricted.
- Upgrades. These frames provide some changes and upgrades compared to factory frames. P80 frames made for Glock® handguns feature an upgraded grip texture, modified grip angle that's more comfortable, and double-undercut trigger guards. The 1911 frames are made from forged 7075-T6 aluminum, reducing weight compared to a steel frame by 50%.
- Easy to machine. Completing either type of pistol frame requires basic tools you may already own, like a vise, hand drill, and files. Each P80 frame includes the finishing jig and necessary tooling bits, plus easy-to-follow instructions. Each 1911 frame requires the Stealth Arms 80% jig, which also comes with simple instructions. No experience is required to complete either frame blank.
How to Complete Your 80% Frame
Whether selecting a P80 or 1911 frame, the fabrication steps are generally the same:
- Cut the slide rails
- Cut the barrel seat
- Drill the pin holes
Total machining time with hand tools averages around 1 hour for new or first-time builders. The P80 frames can be cut with a Dremel and small cutting wheel or snips, with round files used for final fitment. The 1911's 80% jig provides the cutting tool for the frame. Both jigs come with the required drill bits for completing the pin holes for installing your pistol's components.
Your custom pistol build awaits.
