MIM Gun Parts Analysis - Under Microscope

Posted this for George Smith (EGW Guns) at another forum, and thought I'd post it here for informational purposes. I think this simply supports the common consensus here to buy the best weapons you can afford. For those that are unfamiliar, MIM stands for metal injection molded.

Shops like Les Baer, RRA, and others that have had parts analyzed, refuse to use MIM.

Through porosity found on another sear. The long slices are hardness tester marks.

Long void in another brand mim sear.

Unrelated - Imported extractor made with what appears to be cold rolled bar stock with horrible voids running the length.

Inside look at how MIM is actually made.
