They still have some at CMP. Not as many as there use to be. Here is the link to the CMP Member Market Place in case you are interested. Then there is also the CMP Auctions, but they get pretty pricey for my blood, but a go there to look anyway.

I still shoot it but not very often. I have been putting together items that would have been worn into battle by a soldier in 1943. Took a while to find the right bayonet and scabbard. One thing I haven't found is the correct sling. The one I need is highly sought after. Last one I lost in auction went for over $300. But I still am looking with high hopes. One piece at a time.
I really want to create a nice display for the M1 and the accessories when I retire. I have seen some amazing displays that people have put together.
