Just doing a bit of fall cleaning and found I have no guns to fit these, so hope to sell them to someone that can put them to use. If someone does the research to figure out what they will fit, please feel free to post it. 4) I have no idea what these grips might be for. They appear to be some sort of plastic with the inside being filled/bedded with some sort of rigid foam. They do not have any sort of marking on the inside unless it is covered by the bedding material. The screw is included. $15 shipped Let me know if you have questions.
