Subcompact Pistol Kit

Subcompact Pistol Kit

A subcompact pistol is the ultimate daily carry and personal defense weapon. But building a reliable handgun in such a small profile requires quality components, and operating it requires you, the shooter, to be confident in its function and form. The best way to check all these boxes is to simply build the thing yourself. We put together these subcompact 80% pistol kits just for that reason. These kits include all the parts and tools you need to fabricate your new firearm in a single afternoon, no experience or FFL required.

What's Included With Your Pistol Kit

Each pistol kit includes the following components:

  • 80% pistol frame
  • Barrel w/ rod/spring
  • Slide assembly
  • Trigger assembly
  • (1) magazine
  • Iron sights

Polymer80 Subcompact Kits also include the required finishing jig, drill bits, and instructions for fabricating the included 80% frame. That means you'll have all the parts required for completing your pistol and taking it to the range.

Completing Your 80% Frame

Completing your 80% frame requires simple procedures: Using some drill bits, you'll drill pin holes for the parts kit, trigger, and various components you need to install on the frame. You'll also need to cut grooves into the frame to allow for the installation of the barrel and slide. These steps require no specialty tools and little to no experience.

Pistol Builder's FAQ

Is building a handgun at home legal?

Under federal law, yes. The ATF says you do not need a license to build a gun at home for personal use. No FFL is required, nor is a background check or paperwork.

Are these kits legal to buy and own?

Under federal law, yes. The included components in each compact pistol kit are not legally considered firearms under federal law, including the 80% frame. The frame is normally the component of a gun that's considered a firearm and requires a serial number, but these units are not functional. The frames in these haven't yet been fabricated by you, the individual builder, so they aren't considered firearms until you begin fabricating them.

What about state laws?

Certain states have restricted or outright banned gun-making kits like these. State and local laws and ordinances also change frequently, so you must first check our Shipping & Returns Policy before ordering to determine whether we can ship to your state. Before buying or building a firearm, consult with an attorney or legal counsel if you have questions.

What tools do I need to finish my 80% frame?

All compact 80% frames are designed to be cut and drilled with basic tools you may already own: A vise is required for securing the frame and jig, and you'll need an electric hand drill to make the pin holes for your parts installation. Polymer frames can be completed with a Dremel and cutting wheel or snips, plus some round files for final fitment.
