Consecutively Manufactured MIM Breech Face Inserts Paper

I recently published a paper on consecutively manufactured metal injection molded (MIM) breech face inserts found in the Smith & Wesson M&P Shield EZ M2.0 pistol. You can purchase the article here and get the downloadable PDF to read. The article will not only show my findings if MIM-produced breech faces are distinguishable from one another, but it will also explain the MIM process in great detail.  Just as important as knowing the process, you will be able to learn about the different markings found on parts made through any molding method and the markings’ significance to the examiner.
