The pistol and magazine holsters are for a Sig P320 XCarry Legion, as well as a Sig P365X. I checked the top of my TLR7A for the P320 XCarry Legion and it's a UNIV-1. I believe The P365X would be the same mold as the P365XL, but if you have a specific mold for the P365X please use that. I think the only difference is the slide on the P365XL is a smidge longer and the P365X is optics ready (although I'm not using optics).
