Have a dual illuminated RM08G on a Glock 34 and an auto adjust RM06 on a Glock 19.
The RM08G works very well outdoors, love the triangle reticle for its ability to be either precision mode or fast. Its weaknesses are indoor & nighttime use where the reticle is too dim.
The RM06 works perfect in any lighting condition and is on the carry G19 because of that advantage.
No batteries, great reticle shape makes the dual illuminated nice for range work.
Have been using the 34 for 3G but am trying the 19 for next week's match.
