RevolverGuy.com is in the midst of a pretty in-depth series on MIM parts with a focus on S&W revolvers. I found it thought provoking and I thought the folks here might find it interesting as well.
Part I: https://revolverguy.com/all-about-mi...ne/#more-10563
Part II: https://revolverguy.com/all-about-mim-part-two/
Part III isn’t up yet but I’ll update once it is available.
