One of the weirdest moments I’ve had in the “gun space” was actually in my old employer’s (aerospace industry) break room. The young engineers, old-timer machinists, and assorted office nerds (younger me included) were BS’ing about gun stuff. Everyone was whinging about MIM parts in guns while they made their paychecks making MIM parts for military birds, commercial airliners, etc.
It’s never a MIM issue, it’s always a QA/QC issue and how motivated the folks on the floor are to verify their products.
