Questions & Answers
Will this fit the Sig Sauer Xfive P226 Reserve? TY

No. This is specifically their new sig loc system, which is only compatible with the new P211 GTO and mostly new 2025 models only.
Make sure whatever 2025 sig you purchase is SIGLOC. This is their new thing. Confusing but go to their site and read about it. It’s kind of like when Springfield introduced the echelon and you don’t need an adapter plate for optics. It just goes directly to the slide. That is the concept here and the screws bolt from inside the bottom of the slide for the Sigloc. As I said, there are pretty much only two guns of theirs that are compatible for it at this point in time do your research.
