I'm quite sure the masters Coffin maker & Pettifogger will advise
The gun is " adequate " and safe to shoot as new in box, for casual shooting.
for the riggers of heavy shooting or competition ,
* there are areas to address....*as mentioned the arbor OAL should be addressed , brings the gun back to the exact spacing each time the gun has the barrel off.
springs , bolt rise & lock up, timing perfected, all of this will aid the longevity of the gun in heavy uses.
I mentioned earlier I have some 2nd Gens. that have seen a lot of shooting
one, for example was purchase NIB in 1977 , It has been used all these years , in 2004 I purchased a R&D cylinder for it.
It has been in it for the 12 or so years... with either Black Hills 45 ammo smokeless , or 45 Schofield BP reloads
Next year it will be 40 years old.... a couple of years ago I sold off the Faux Ivory Buffalo Bros. grips and reinstalled the original
grips to the piece ....
I am contemplating for its 40 Birthday to return it to percussion , and sell the R&D , somehow it seems fitting to do that
(as an aside I'd like to point out
....*Tuning* as it were , is something any gun might see, whether it be a Colt or Glock, AR platform
S&W whatever, all will benefit in the longevity in
heavy use.
Of course in the case of Sock Drawer & safe queens not so much
