It depends on the distance of the targets
IMHO...
Over 20 meters...optics win
10-15ish meters it's a wash
under 10 meters...irons sites are faster (optics just get in the way)
...and where the hell have you been hiding??
have you checked the CCG c-more mount at CRAFM? I got it and currently havign my frame drilled for it. At first glance, it seems to have eleminated the short range problems, the c-more window is almost dragging on the slide
