 FAQ: Your Glock Build Questions Answered

Q1: What is the most popular Glock to build?

A1: The Glock 19 (G19) is the most popular Glock-style firearm to build. Its compact size makes it ideal for a wide range of uses, and it has the largest aftermarket support for parts, 80% kits, and 3D printable files.

Q2: What is a Glock 80% kit?

A2: A Glock 80% kit is an all-in-one package that allows you to build a complete, functional Glock-style pistol. It includes an 80% frame (which is not legally a firearm), a jig for finishing the frame, and all the other parts (slide, barrel, internals) required for assembly.

Q3: Are Glock 80% kits legal in the USA?

A3: Under federal law, building a firearm for personal use from an 80% kit is legal for any non-prohibited person. However, some states (like California and New York) have passed laws restricting or banning these kits. You must verify your specific state and local laws. Resources like the Giffords Law Center can be a starting point for your research.

Q4: What parts are interchangeable between a G19 and a G17?

A4: The trigger mechanism, pins, slide lock, and magazine catch are generally interchangeable between a G19 and a G17 (Gen 3). However, the slide, barrel, recoil spring, and frame are model-specific due to their different lengths.

Q5: What is the difference between an 80% build and a 3D printed build?

A5: An 80% build uses a commercially made polymer or aluminum frame that you finish by drilling holes and milling. A 3D printed build involves creating the entire frame from scratch on a 3D printer using a digital file. Both result in a privately made firearm.
