I've been tempted by the smaller size of the JPoint size, but everytime I played with them inside Cabelas the floresent lights but a glare on the plastic screen, and have to adjust the position of the sight in my hand to find the dot. The tube style dots just seem to line up naturally for me. Im guessing if the sight was mounted on gun with a repeatable grip position maybe I could find the dot quicker. I gave up and bought the Aimpoint Micro tube style for its reduced size. Its nice but the Ultra Dot, is a third of the price, and you can adjust the dot size,
