Although high quality red dot sights are now considered by most to be an essential item for those running a carbine, their use with duty pistols is still relatively rare (aside from the specialized roles of competition, hunting, etc.)
As a greater variety of rugged, very compact RDS come to market, do you believe that we will see a change in the commonality of the compact, pistol-mounted RDS? I am referring primarily to the Trijicon RMR as that is what I am most familier with, but I realize that there are several other RDS designed or acceptible for use on handguns.
I am aware that use of a RDS on a handgun utilized for concealed carry presents a certain set of problems (holster selection being one, at least in the short term), but I think for a LE duty pistol it would be very functional. I have always felt that the nature of the service pistol doesn't necessarily require a particularly compact weapon and is best served with functional enhancements, such as weapon lights.
Disclaimer: I have had limited range time with pistol mounted RDS, have not trained with them, and currently do not own any handguns utilizing them. I am simply interested in future utilization of this concept.
