I LOVE it! This is my first other-than-'iron' sight for a pistol, and my initial experience is VERY positive. It cost only $308, delivered, including the mount, and I installed it myself, but one needs a sight pusher for that. Group sizes are about a third of what they were, and today I shot my 1st three bugholes at 10 yards. The dot is PLENTY bright in the harsh desert sunlight, and the gun is still low enough to be carried in my Tommy's bellybag.
