Big dots have become my favorite handgun sights. - XS Sight Systems DXW Big Dot Sight - Sig Sauer

I started using XS Big Dots on a Glock a few years ago and quickly discovered they are the fastest shooting sights I have used. My brain does not need time to process aligning three dots or a square peg in a square slot. You just rest the golf ball in the land and boom, on target. I have heard folks say they are not very precise but I shoot out to 20 yards and can get the job done so I will leave that group to the paper punchers and spotting scopes. Bottom line, now matter what handgun you have these sights are perfect for CQB if that is the goal.
