I purchased my Model 65-3" RB while at the S&W armorers' school back in the 80s. After fixing a minor internal flaw. I discovered that the gun didn't quite shoot to the sights. One of the S&W armorers took the gun and "babbitized" it, to use his lingo. Afterward, the gun always shot to the sights.

My feeling is that taking a babbit to a revolver requires experience and skill. The amount of babbitizing needed is always too small to see with the naked eye so I would be inclined not to try it myself.

Incidentally, the 7-day revolver armorers' school I attended did not teach the use of the babbit.
