I've had a Millett SP1 on my Mk III Hunter since just after I bought it about 5 years ago. This week, I took it off. It was boring to shoot, felt top-heavy, and despite what others say about red dots, it doesn't seem to get me on target quicker - just the opposite. With the factory iron sights (notch in the back, hi-viz thingy up front) I'm on the target more quickly, though not precisely. I can make the soda can dance all day. I'm happy. With the red dot, its constant jittering bothers me and I tend to try to correct to a degree of precision that I don't need in freehand pistol shooting. If punching a single hole at 25y is my goal, I should get my rifle. Ya know what I'm saying? If I were trying to shoot in a bullseye match then maybe it'd be better having it on there ... but if I were shooting in a bullseye match I'd probably be using something better than a Millett SP1 (which is not a bad red dot for its price). I'm holding onto the SP1, to put on a 10/22 carbine. Maybe it'll work better for me there. Anyone else come back to iron sights after putting a red dot on their pistol?
