Holster stuff- - -
mec, that is a beautiful piece.
With regard to your use of nylon holsters--
Please be aware that the weave of hard-laid nylon catches and holds stuff--sand, dirt, grease, oil, powder fouling and who-knows-what else. Then the nylon serves as a (mild) abrasive. If the engraving is as pretty as it appears, you might, after a time, knock off some of the sharp edges of the scrolls and so forth.
I do believe that a lined leather holster might be less problem for the finish of your fine revolver than nylon.
Best regards,
Johnny
