Can we sticky this?MIM parts are in most rifles and shotguns, including some high-end models, and many many production revolvers. Firing mechanisms, trigger guards, safeties, barrel bands, locks, operating levers, sights, etc.
But the MIM scare is only within our pistol circles, so it's the only place you see people freak out.
Its funny that some pistol owners spend hundreds of dollars to rid their handguns of MIM parts, but shoot shotguns and rifles proudly without ever knowing that their hands have touched MIM. In those moments, ignorance is bliss.
