cracked M1 Stock

Sounds like the bolt impacted the rear of the stock and cracked it. Look for a dent at the top of the inletting in the back.

Don't glue that with super glue. Best way to fix the stock is to inject Brownells acraglas into the crack with a syringe, being certain you have 100% glue contact with the crack and then clamping it properly.
Done many of these, the crack will not come back.

As far as why the rifle doubled, not enough info present. Do check the operation of your trigger group outside the rifle.

The best way to replace it with USGI wood is buy from Dupage.

If you want the best shooter stock, get a laminated stock from Dupage.

I've "fixed" two cracked stocks. One is s beautiful tiger striped stock my college ROTC drill team broke in about 1969. Crack went all the way top to bottom right in the middle where the clip goes on one side. Dug it out of the trash in the armory... I packed it with Elmers epoxy (strongest glue I had back then...) and taped it with masking tape. Cure time 31 years. Put it on a CMP rack grade Winchester, have run 300~ rds through it, still fine.

The other was a cracked FN-49 stock - crack running from just aft of the trigger guard to the top of the stock about the middle of the mag well. I believe in both cases the guns hit the pavement butt first, the FN courtesy of a poor packing job and careless shipping service. I degreased it as best I could with lacquer thinner, injected Gorilla Glue CA, and clamped the repair. 15 rd. Test fire was ok. If you like your stock I would suggest you try a repair, if that is unsat you can always replace it.
