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:

  • 80% Polymer Frame: Made from a high-strength, reinforced polymer, designed for durability.
  • Enhanced Ergonomics: The frame features design improvements for a comfortable and secure grip.
  • Grip Texture: Comes with an aggressive standard grip texture that can also be customized with stippling.
  • Accessory Rail: Includes a Picatinny/STANAG compliant rail for mounting lights or other accessories.
  • Serialization Plate: A blank plate for serialization as required by law.
  • Locking Block Rail System (LBRS): Stainless steel construction for reliable operation.
  • Rear Rail Module (RRM): Stainless steel, provides a secure mounting point for the slide.
  • Hardened Pins: Included for both the LBRS and RRM.
  • Finishing Jig and Drill Bits: Everything you need to complete the final machining steps.

Compatibility

The PF45 is designed to work with several readily available components. It’s compatible with:

  • Glock 20SF/21SF Slide Assemblies: Use your existing slide or purchase a compatible one.
  • Glock 20SF/21SF Magazines: Accepts standard Glock magazines.

Important Note: If you plan to use Lone Wolf Dist. completion parts, be sure they are GEN 3. Using other generations can cause damage and will void the Polymer80 warranty. Double-check all components before assembly. Iowa Gun Shop is not responsible for issues caused by incorrect parts installation.

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.
