A frame is generally a serialized part for the firearm. If it isn’t it can be used as one of the primary functional component housings for the firearm. We cover a generous portion of the market by offering aftermarket and (in some cases) OEM frames which will allow you to replace a broken or abused frame on your own without having to utilize factory frame replacement or will give you a chance to customize the frame to your liking. Because most of the frames that are available will be serialized and are a "controlled" component of the firearms industry, you will need to have the part transferred to an FFL dealer in your area. For those parts that are frame and are not regulated, you will be able to utilize the part to improve upon the customizability of the firearm and give you a choice for how you use your gun.
