I bought a Rock Island .45 Commander 1911 and it's accurate and a great shooter but I would like to install bigger sights. I could have bought the RI version that had nicer sights but it had a beavertail and perforated trigger and I wanted a gun that looked like Military GI/old school. The rear sight is dove tailed in and I'm sure I could do myself but the front is staked in place and is a little trickier. I saw some Colt high visibility sights on Midway for about 25 bucks, anyone know a good Smith in OKC that could install these?
