"older, or worn firearms"

Uh, you're going to have to provide a multitude of examples.

I know of any number of antique firearms that shoot just fine.

An example ~ one will prove the whole case. Tim McVeigh had a broken or mismatched home-patched pistol on theseat beside him when the cops stopped him.

The leftwingtards were ready to blame his pistol until they found out how nasty it was. This one was so bad they gave up that line of attack.

BTW, not all old and nasty firearms are antiques ~ many of them are simply old and nasty!
