Was at the range this morning, and shot a guys Colt with the blacked out Heine slants. Sights were great, very easy to get a nice sight picture, much better than my Trijicon night sights. Anyone else like these sights? Any other sights to recommend? I'm looking purely to shoot this gun at the range 20-75 feet. Secondly, would you have Heine install or is this easy enough for a local gunsmith?
