Be realistic about your wants and needs. There is a difference between field stripping and disassembly. As a child I took a clock apart. Far as I know, that clock is still in pieces. I will field strip a firearm for cleaning/maintenance. But I am not tearing it down to individual pieces. The exceptions being an unmentionable bolt assembly or magazine. Certainly, I will not take a revolver down to component parts. I am 75 with age related eye disease and 5 thumbs per hand. I would wind up taking the revolver parts in a bucket to a gun smith.
