Ahh the one exception. Springfield Armory's infamous sintered MIM metal. Look at that break. that is a classic Metal Injection Molding failure.Lulz. Are we pretending that double charges, etc. are because of "old plastic" or that metal guns survive it?
Woopsie.
Anyway, I own and use both with no strong preference.
Seriously google Springfield Armory MIM sometime.
To be clear, when the process is done right.. it WORKS. But the idiots at SAI are rather known for bad QA on the process and improperly done MIM parts make it out of there all the time.
