Carry Size Pistol Kit
A carry-size pistol should be configured exactly how you prefer. After all, if the time comes to draw in self-defense, you need to be confident behind the trigger knowing your weapon of choice will get the job done. These kits are carefully configured using high-quality, factory or aftermarket U.S.-made parts guaranteed to be compatible with their "retail" platform's counterparts. We carry complete pistol kits for the Sig P320 "carry-size" configuration designed for daily concealment.
What's Included With Your Pistol Kit

- 80% fire control unit
- Frame or "grip module"
- Barrel w/ rod/spring
- Slide assembly
- Trigger assembly
- (1) magazine
- Iron sights
Completing Your 80% Frame
Completing your 80% frame requires a few 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 and bend metal tabs into the FCU 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 pistol kit are not legally considered firearms under federal law, including the 80% FCU. 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 80% frames and units 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. The P320 80% chassis requires a Dremel, hammer, and hand drill or drill press.
