One assumes that he is working with iron meteorites. If so, then the iron is softer than the chromium molybdenum steel actually used in modern firearms. It would be too soft for use on any part of a gun that would contact either the casing or the bullet. If he is working with silicon meteorites, then the material is too brittle for construction of a working firearm.

They have tried similar things with knives. Ceramic blades are too brittle and delicate. Titanium blades are too soft and won't hold an edge. It's pretty hard to beat plain old hardened steel.

Steel is a difficult material to work with, and much of what we know now has been a process of trial and error going back from ancient rome to now on steel production. Titanium on the other hand can make amazing knife blades, I think the too soft is due to the grade used, because good grade titanium has to be cut from a pure block, much like nasa does, which is far too expensive for the average knife to be made.

No, the successful blades have used titanium alloys and they are still soft, even those on the $500 knives. They are useful for applications that require a non magnetic product, but they aren't great knives.
