Got a Walther PPQ Q5. I've been carrying around a drool bucket for so long that my darling Wife er, Santa finally got me one to shut me up. I got to shoot a new one at an indoor range and was fortunate enough to find out that one of the guys there was a member of the Walther team. He shot the PPQ Q5 with a few personal changes. Great fun! He had what I think was a 3 moa RMR. Super low flair great acquisition. I had a fantastic time but forgot to look or ask what RMR he had. So here I am. What RMR would you pick. The gun comes with all the attachments for about any red dot Which is really nice. I tend to lean toward Vortex but I like to hear ya.
