To the OP, by all means yes on a RDS for conceal carry if your eyes are getting dim. As mentioned, practice at the range until you feel comfortable at a good distance besides PBR and shoot it until it's muscle memory. The RDS on the gun I may carry if I did conceal carry but I probably don't,,,,,,,,,,,,,,
does not print even in summer and does not in any way shape or form snag on anything I'm wearing.
For Annihilator, IMO......if you can co-witness even 1/3rd with your RDS, I see no reason at all to have a laser light on the gun. A flash light, yes but not a RDS, laser light and a flashlight. Two beams regardless of their color is asking for trouble in a heartbeat confrontation moment. Laser and flashlight or RDS and flashlight. Not the trio.
