I went with the Trijicon RMR RM06 after waiting for about a year to get more information about the Leupold Deltapoint Pro. After information trickled out, I spoke a little with Trent Zimmer over at Unity Tactical, and he suggested that I just go ahead and go with the RMR over the Deltapoint Pro, as there was still a significantly lead time before general release of the Deltapoint Pro, along with the fact that it is a taller optic than the RMR, and would require even taller BUIS than the RMR. The original hope had been that I'd be able to mount the Deltapoint Pro like the Deltapoint, in that it wouldn't need a separate adapter plate for the P30LS, but that didn't work out as I had hoped. I had Mark Housel over at L&M Precision do the work for me; he'll be getting a second P30LS from me soon enough, too.
I've not found myself slowed any compared to my irons (Hienies with the front sight painted bright orange) while running my standard practice drill (3×5 index cards at 7 yards); the caveat to that is that I've never been a very fast shooter (~2.2 seconds from the appendix concealed, ~.45 second splits, ~2.4 second reloads). I have found myself more consistent, though; with irons, when pushing myself, I had a habit of dropping shots just half an inch low (which was pretty infuriating). I've also found the laser dot to be less distracting with the RMR compared to the irons. The main area I've found myself much slower in acquiring a sight picture is when starting from a position I don't have a well developed index for, e.g., drawing SHO or WHO. However, I've found that the feedback given by the RMR means I'm breaking the shot much faster than with irons, after I've acquired the sight picture, so speed is a wash, while there is a definite accuracy edge with the RMR.
I purposely chose an adjustable RMR because of concerns of dot washout from my WML; this proved to be a valid issue, as the RM06 run in auto mode does wash out quite easily indoors when used in conjunction with the X400U. I currently keep it at the 11th brightness setting (out of 12); I was keeping it at 10 originally, as it was perfect for indoor, but it proved to be too dim outdoors in direct sunlight, where 12 was best, but had massive bloom outside of anything in direct sunlight. Beyond that, the only hardware issue I've had is that the RMR had on two separate occasion somehow gotten back to auto mode.
And yes, this is what I carry for EDC (including the watch, though normally in a more conventional spot).
