Hope you don't mind me responding too. I haven't had too much trouble losing it, so I don't think it's too small. I think it's supposed to make it easier to shoot small targets and/or longer (than CQB) ranges. The fiber optics seem to keep it bright enough, but I hear it gets washed out if you're shooting from a dark area into a bright one. I tried just sighting such a situation and I'm confident with some practice you can get around it fairly well. Overall I'm happy with mine and have no complaints.
Dan, thats an awfully small dot and not that bright, how well does it work when shooting in the direction of the sun, or other bright situations?
I only ask because it would seem to me that if it was too bright out the dot would be lost.
