Proper sintering allows ample time for atomic diffusion to decrease the voids in the material to a point where they are no longer an issue. This is why the part always gets smaller after sintering.

I would much rathar have a quality MIM part which was properly sintered after formation and made with wuality raw materials than a part made of cheap mild steel billet which was hot forged and then not properly tempered.l

As for being able to tell a MIM part from a part made of bar stock, it all depends on the type and temper of the bar stock part and they type of fracture.

Just like with aluminum parts, one manufacturers "high strength" aluminum might be a 5052-H32 with a yield strength of 28ksi where anothers could be 6061-T6 with a yield of 40ksi. Everything is relative.

Secondly, to push the original post a bit further down the pike, are these MIM parts a serious issue and should these parts be replaced before the weapon malfunctions when you need it most?

Metal Injection Molding.

Eg, parts made in a mold, and not cut from bar stock.
