Polymer80 PF45 80% Large Frame Kit - FDE
About this product
If you're planning a custom .45 ACP build, the Polymer80 PF45 Large Frame Kit in Flat Dark Earth is a solid starting point. This is an 80% frame, meaning it requires some final machining to be fully functional – it’s a project for those comfortable with firearm building and familiar with Iowa’s laws regarding such projects.
What's Included
This kit provides the core components you need to complete a large frame .45 ACP pistol. Here's a breakdown of what you get:

Iowa Considerations
This kit is popular for Iowans building a pistol for home defense, concealed carry (with proper permitting), or general range use. The .45 ACP cartridge is a practical choice for self-defense and offers good stopping power. Remember to familiarize yourself with all applicable Iowa laws and regulations before starting your build.
