Rovert, that's $120 for all 3-dots, including drilling the front sight *and* the dovetailed rear sight. It's $20 to $30 more from trijicon, but you can get a coupon from Ajax Grips for $80 for the sights and have Tool Tech install them, which costs you ~$30-$40 for installation and shipping- that's who Trijicon uses as far as I understand.Thull, that's good to know. Problem is the cost. $120 plus the cost of the rear sight will probably wind up being a $250 job, when it's all over with. That's pretty pricey, but in the end, it's meaningless if you don't care about night sites.
