Fixing to send my G27 slide and Trijicon RMR01 to Doug @ ATEi to have the slide milled for the RMR and Trituim Suppressor sights installed.
I have a Dual illuminated RMR on my Trijicon Accupoint.
Doug suggested the Battery powered over the Dual illuminated RMR.
i havent seen their rmr fiber optic but if its even remotely like the acog i would go fiber. the chevron on my acog is brighter in bright sun than my wife's aimpoint on highest setting.
its worth looking at one before buying if possible to see for yourself

The problem with being stupid is you cannot simply decide to stop doing dumb things...
I have a RMR Dual Illuminated on my LaRue mount with my Trijicon Accupoint 3-9x40.
For a pistol I'm going with Trijicon's RMR RM 06 adjustable RMR. This one has brightness settings and can be turned on/off.
