I've now done three range sessions with *my* new 686SSR Pro Series. This resulted in me abandoning the Dawson FO sight in favor of the original Red Ramp sight that the gun came with. I found that the Dawson sight resulted (for me - YMMV) in inconsistency. I attribute this to the small size of the Dawson FO dot. I think that for the Dawson sight to work well I would need a different rear sight with a narrower notch. The Red-Ramp front sight is easy to place and I can get a ragged bull's-eye hole going with it. The Dawson sight is a fine piece of kit, but it did not work for me with the OEM rear sight on the 686SSR.
