“Love my XS Big Dots! Nothing compares in a defensive situation. Fast sight acquisition is key when your life is on the line and big dots give you the best opportunity at a quick sight picture. I didn’t know what I was missing till I tried XS for myself. I’d recommend them to anyone serious about protecting themselves. Here’s a pic of big dots on my M&P Shield next to a spare mag and my trusty Surefire EB1.” -Hayden F., TX.
