I just picked up a 52-2 in really great condition. Took it apart as the gun has been in storage for over 15+ years with the slide locked back. My 1st question is how long should the recoil spring be? I'm thinking that it has been compressed for so long this may affect operation.
Also, is this a "normal" discoloration on the barrel? I have never seen this before and want to be sure there is no issue with the barrel..When I get it all back together I will post some pic's..20181008_150941[1].jpg
