The key difference between a P80 (Polymer80) and a Glock lies in their origins, legal classifications, and assembly processes, though they are closely related in design. Glocks are factory-manufactured firearms made by Glock GmbH, an Austrian company known for its reliable, mass-produced pistols. They come pre-assembled and ready to use, with all parts meeting strict factory specifications. Glocks are sold as serialized firearms, meaning each gun has a unique serial number that can be traced, and their purchase requires a background check in compliance with local laws.
In contrast, a P80 typically refers to a Polymer80 kit, which is an unfinished firearm frame that requires further assembly and machining by the buyer to become functional. These kits are sold as “80% frames” or “receiver blanks,” meaning they are not considered firearms under federal law until completed. This allows buyers to purchase them without a background check or serialization (though some states have introduced regulations requiring serialization or prohibiting their sale). Building a P80 requires additional tools and expertise, as the user must drill, mill, and fit various components, which allows for more customization.
While the finished product of a P80 build often resembles a Glock pistol and can use Glock-compatible parts, the key distinctions are the legal classification and the DIY nature of the P80. Owning or assembling a P80 requires careful adherence to federal and state laws, including restrictions on resale or intent to manufacture without proper licensing. On the other hand, Glocks are ready-to-use firearms purchased through traditional channels, with warranties and factory support included.
