No offense to any of the mechanical engineers but I wouldn't let most of the touch my guns let alone disassemble them. Most can draw it/assemble on a computer ,but don't know which end of a hammer to hold. Not all, just the ones they hire at my work.
Based on the number of times I've seen a brand new gun carried inside a Ziploc baggie for me to reassemble...No. Owning a gun does not bring about a magical transformation of mechanical skills.
