I was given a H&R 999 sportsman by a aunt of mine that bought it in the early 90s. She didn't want it anymore because she could not hit anything with it, so she gave it to me. Upon inspection I noticed it didn't have a rear sight. Both the adjustment screws are still there but no sight blade. No wonder she couldn't hit anything. Anyone know where I can get a replacement? And is there anything I need to know about the gun? I only own 3 revolvers and two of them being a little older and given to me from family so I do not know much about them.
