Never really had any issues with the Bearcats over the years seldom had to polish the lockwork,sear, trigger ,etc...... not exactly a target revolver or a CCW piece ( home defense) easy enough to put a glob of something ( yes even toothpaste) but we used the white grease ( lubriplate) what they put on camshafts for fitting, work it into the action and just use the gun, let all the parts "match/mesh" to themselves, NO need for any trick stuff of jigs and fixtures, we never did since early 1960s and having owned and run 3 different gun ( service ) shops.......
I will add ,knowing the nature of the "beast" ( stainless steel) due to tolerences and the material itself, it tends to burr, and gotta be careful NOT to cut yourself on "sharp edges" and Ruger has been making some 'New Bearcats' in 'stainless' but I have NOT had to work on any of them as I am now retired,,,,,,,,,,,,,,Good luck
