@riceyhotstunna5921 ... I run the Lobos Industries optic mount on all my Ruger Mark IV pistols. And yes, I like them alot...they're the best optic mount that I've found for the Ruger Mark series pistol. If they're not in stock, you can sign up for a notification that'll let you know when they get more made, and it usually doesn't take long. He makes them in batches for many of the different optic footprints.
