Hello guys and gals. I'm new to this form and I'm hoping I can find a answer about the 1911 I got from my dad. When I got it, I noticed that it had no front or rear sights. I have taken it to three places trying to find sights for it and no one can find anything. The notch for the rear sight is huge. In all the pictures I've found online, none of them have a real sight recess this big. Any help would be greatly appreciated. Thank you.
