Bigger than picture shows - VISM Flipdot Pro Red Dot Reflex Optic

Having a sleek and thin design is a big deal for a carry weapon. This is my biggest issue. It was not a little, but much larger than picture shows. The pic must be a G20. 45cal or 10mm or something because I put this on a G17 and its almost too big. Other than that it seems pretty decent. Almost want to give it 4 stars
