Hey guys , just got a 23 the other day (gen3 brand new -- $479 !!) and I want to put an rmr on it ... I have questions .. - There are many rmrs avaible (as far as I can see) , I don't need a fancy one just a basic .. Which one would be the best buy and anyone know who has the best price? - Is the mount do-able ? I don't want to mill the slide if I don't have to ... I'm not worried about the rear sight/cwitness Help would be appreciated !!
