I just got my RM07 mounted - too bad for me the elevation adjuster did not move in either direction. But as it was it was pretty close so I tried it out. I have been using laser sights for some time and my interest in the RM07 was for daytime shooting. The dot seemed to be pretty easy to see and 'natural' to point. For those who have been using iron (open) sights it could be a major change - I have found it near impossible to switch back and forth from iron sights to laser/red dot. You have to train to see either the front sight or the target.
I am getting a replacement for the RM07 but need a second red dot (another Glock) and am looking at the STS and would love to hear from anyone who has used this.
