It Fits!
So after several days of emails and trips to three local gun shops - including the Pro Sig Sauer dealer who was unable to provide me with the correct answer. It was you guys that finally led me to the correct part I needed to properly mount my Trijicon RMR to my new “Optics Ready” 24 Sig Sauer P220 Legion. So I emailed Trijicon, Sig Sauer, and C&H Precision. Trijicon surprisingly didn’t know.. C&H said they didn’t have a plate for the P220 Legion.. (they actually do..) And Sig recommended their “sealing plate” which doesn’t provide the mounting posts that help mitigate the shear stress on the mounting fasteners. So! All that said - if you own a new Optics Ready Sig P220 Legion, order the C&H Precision SG69-RSH-FIL adapter/mounting/fill plate. That’s what you need! It’s crazy that it has taken this much beavering around to finally come to the answer.. Roll Tide! 💥🤪🇺🇸
