Hey Abilene!! And Buxton Guy,
Yep. That is absolutely a TON of stuff. I, by training and nature, am one who looks at a mechanical appliance and searches out the imperfections and then fix's them. So is Pettifogger. If there is a failing, we WILL find at and tell you how to fix it. ALL of it. HOWEVER:
THE biggie is to clean up the Barrel to arbor fit so it goes together and comes apart reasonably easy and fix the Barrel to Arbor fit. I found a couple lustrum ago, simply dropping a 10mm split washer (I like stainless) down the Arbor bore of the barrel would correct the Barrel to Arbor fit to neat perfect. Your gun will love ya for it.
The rest of that "a lot of stuff" applies if your going to run the gun hard in reaching for the Brass Ring. I do suggest however, you also consider reducing the Main Spring. VTI Gunparts and Brownells have rather nice reduced Main Springs as does Wolff. Your going to have a gob of fun playing with your new gun.
