The first issue is fishing for the dot. The second issue is that dot moves like a mother. Pistols don't have the 3rd point of contact to your body for stability.
I'll stick with traditional pistol sights. Hell, I even like irons over a red dot on an AR
This is very true. I was shooting GSSF matches with my G34 in Unlimited. I was also shooting higher scores on the same course of fire with my G17L with a Dawson tritium front and plain black competition rear. GSSF indoor league does have a time component, but it's not part of your score, your score is purely based on hits. I was scoring higher with irons so I traded the G34 off.
I do like me some Aimpoint on my ARs tho...
