I have had this for a long time and was using the lower with a 22 upper. I would like to get it reconditioned and start shooting 45’s with it again. Anyone know anything about it? I did some searching but didn’t find much and nothing about the Survivalist model. Low serial number, 4197. I would at least like to get a new rear sight but don’t know what cut it is. From what I remember it was pretty accurate except for the sight being off. It shot really high and I drifted it out but never got around to replacing it. Thanks for any help or info anyone has.
