self install
i bought this to replace the factory sight on my SR 1911. I watched Dave's Youtube video for dovetail front sight install a couple of times. All I needed was a good , flat sanding block and a small file (that I already had) and a little patience. I followed his instruction and his tips on how not to damage the slide. I took about a half hour to put it on , then locktited it in place. The sight works awesome , now I can see easily where my gun is aimed. I can't believe how bright it is, and theres no blurry halo around the sight which i have seen on other guns I've fired. big improvement for a small price.
