After lurking awhile, I guess I'll jump in.
This is not the exact answer to the question, but:
This from the Ruger website,
FREE instruction manuals for all Ruger firearms are available free upon request. Please write: Sturm, Ruger & Company; Lacey Place; Southport, CT 06490. Please specify model for which you require a manual.
I have been having the same question because I am about to do the same thing with a Taurus.
After some research, I decided to get a copy of Gunsmithing : Pistols & Revolvers by Patrick Sweeney. Seems reasonable for $20 compared to the amount of learning I stand to get. If anyone has an opinion about this, please.
If this doesn't get moved to The Smithy forum, You may want to ask there. It seems here is a massive amount of wisdom there.
