Pistol Frames FAQ – Your Guide to Buying Online
What is a pistol frame?
The frame is the serialized lower portion of a handgun. It houses the fire control parts and forms the foundation for the slide, barrel, and magazine.
Do pistol frames require an FFL transfer?
Yes. Frames are considered firearms under federal law and require a background check and transfer through a licensed FFL dealer.
Can I buy a stripped frame and build my own gun?
Yes. Many shooters start with a stripped frame and add slides, barrels, and triggers to complete a custom handgun.
What materials are frames made from?
Polymer is common for low weight and corrosion resistance. Steel and alloy frames are typical in 1911s and competition pistols for added rigidity and recoil control.
What’s the difference between a frame and a receiver?
For pistols, the terms are often used interchangeably. The serialized part legally regarded as the firearm is the frame or receiver.
Are aftermarket frames reliable?
Quality aftermarket frames can match OEM reliability when made to correct specs. Always verify manufacturer tolerances and part compatibility.
Can I customize a pistol frame?
Yes. Frames can be stippled, fitted with new backstraps, or upgraded to accept optics and trigger improvements. Modular systems make swaps easier.
How much do pistol frames cost?
Prices vary by platform and material. Polymer frames are generally less expensive, while steel, alloy, and modular frames cost more.
Are frames interchangeable between models?
Not always. Frames are platform specific. Confirm compatibility before buying, for example a Glock-pattern frame will not fit a SIG slide without matching platform parts.
