    Not sure it would hold up on a Carbine extractor, but look at all the manufacturers now putting MIM (metal injection molding) parts in their guns. New pistols for $200 and they seem to work OK. - Bob

    A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered.  Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle. For the record this is not a moneymaker, I hope just to break even, eventually, at $80/book plus shipping.  In the USA shipping is $5.00 for media mail.  I will accept PayPal, Zelle, MO and good old checks (and cash if you want to stop by for a tour!).  CLICK BANNER to send me a PM for International pricing and shipping.

    Yes they say Glock extractors which are MIM, hold up just fine. I have a few spares but my Glock was made before they switched to MIM so I haven't had any experience yet shooting with them.

    I've never read anything about this subject but I'd bet that the wear and tear on a semi-auto carbine and an M2 must be night and day.

    It would be interesting to see how one of those MIM extractors done with some exotic modern steel would hold up with no heat treatment at all? I'd bet just common 4140 would do just fine. The MIM casting would be a perfect part as opposed to the junky looking Wartime part. It was a troublesome part from the very beginning. Looking closely at one of the surplus extractors made by some contractor during WW2 will disappoint you. They probably don't fit as well as a new MIM part would.

    I had my RIA "Rock" apart a couple years ago. When I first got it, I thought some of the parts (MIM) looked like they were made out of plastic. When I got it apart I found out they weren't! - it's pretty neat for a relatively inexpensive gun. - Bob
