I've got a colt model '91 series 80 that I'd like to fix up. The finish is thin in spots, and I'm not a huge fan of the sights that are on it. Here's a list of what I'd like to do to it: Refinish with a more durable finish, like cerama-coat or duracoat. Replace sights with something better for low-light And since I'm a lefty, I'd like to add an ambi. safety and mag. release. But here's my questions: I'm assuming this gun isn't rare, since it didn't cost me too much when I got it, but would refinishing horribly detract from the value? What are my options for sights? The rear is a standard dovetail, but the front is different. I can't tell how it's attached. Do I need to have a front dovetail cut? How difficult is it to install the safety and mag. release? Is it the kind of thing I could do myself, or would I need to take it in to a gunsmith? How difficult is it to completely disassemble this gun for refinishing? I've taken the slide off the frame for cleaning, but that's as far as I've gotten. And lastly, Is there anything else I should consider replacing, or something that is prone to failure on the series 80's? I'm happy with the accuracy, just not when I'm shooting it. I've seen my brother consistently hit an 8" bull at 50 yards, but he's an Army Ranger, so he gets to play with guns all the time. Thanks in advance for any help. And here's a couple pics, because everybody like pics. And this one's kind of fuzzy, but it kind of shows the front sight.
