Utterly Mad

What do we (american or not) think of this arising issue in the US of the united states rapidly aging military equipment? My stepfather used to be the quartermaster of an armory when he was still in active service (the marines) and showed me his 1911, which he pieced together with the best salvaged parts he could recover from 1911s that had been in use since WW2. Is a 1911 supposed to rattle like his does? Fuck no but from what he says, when he was servicing the armory, most of the 1911s he had were like that. Worn out WW2 relics that had been kept around because it would have been more costly to replace them. I believe they have replaced them by now, but those replacements are starting to wear out and/or are seriously under powered.
