My dad has an old Springfield 1911A1 and the sights are pretty poor and difficult to see. It is in almost new condition. He bought it from the original owner and it doesn't seem like it was shot much at all. He was going to send it off to get new sights but after I showed him some Modern Samurai Project videos, he is very interested in red dots on pistols. Is it possible to get a red dot mounted on his 1911A1, whether direct milled or a mounting plate? Where is a good place to send it to get the work done?
