I am wondering on how to change the dovetail front sight on my Browning Hi-Power Mk III. Would it be a good idea to take it to a gunsmithing shop to have it done? I don't have many gunsmithing tools and am not sure I can do it properly. It's a nice Browning and I don't want to harm it. Is it an easy job? Or should I just have the smith do it properly? How much is a fair price to have this done? Only the front sight will be changed, not the rear. Thank you.
