My holy grail for defensive use has become useable cowitness with normal height sights. I have a 19.5 with RMR and broadsail height suppressor sights, but that’s definitely not where I want to be for smaller defensive guns such as a 43, 43X, 48 or 26.
My 26.5 will probably be the next RDS victim. I’d like to quantify how deep of a cut is needed to do this for a low, compact RDS like a Shield, Swampfox Sentinel or 407k instead of an RMR or RMRcc. It must be possible since the 43X and 48 MOS models do it out of the box.
