Snap caps: recommended or not?

[LBL]

I've always used snap caps and have them for all my shotguns, including my two 16ga Parkers (DHE vintage 1911, VHE vintage 1926). My understanding to this point has been that one should not leave the guns cocked and that dry firing without snap caps can harm the mechanism. My elderly uncle, who passed these two beauties on to me, counsels to the contrary that the Parkers should be stored cocked. Among other reasons it can position the ejector spring mechanism embedded in the forend so that mechanism must be re-cocked in order to assemble the forend to the barrel and receiver. He has tons more experience and expertise than me and is still razor sharp, so I tend to follow his guidance. But for this question it seemed to merit checking this forum, and I’ve found no other threads on this topic. Is there a clear Y/N? Or what are the factors to consider in making one’s decision about storing Parkers cocked vs released with use of snap caps?
