Be brave, repair it. If it goes T...up, then look for a new one.
I fell on my Berretta 20g 687EELL whilt it was in its slip. Result, a nice crack through the pistol grip.
I removed the action, then carefully, as it’s a £2k stock, opened the crack up until the stock split in two.
I checked the two halves fitted back together seamlessly removing any little whiskers of wood that were in the way (inside the join not on the outside where it would leave a gap).
I then degreased the wood, as walnut can be oily, and glued/clamped the break with West System epoxy (the stuff that holds wooden boats together with no screws or nails).
Once the epoxy had set, I carefully sanded the stock, stained it with Rusty Walnut Birchwood Casey stain, then refinished with Trueoil (a couple of rubings with 1200 grit W&D and Trueoil will produce a filler that will fill the grain + any small imperfections around the join. Allow to set between rubs until the imperfections/grain are filled. Then 5 very light coats of Trueoil (I use balled kitchen rol to apply) flattened with wire wool every other coat.
The stock now looks better than new and the repair is completely invisible. It’s also very strong and I know it’ll never come apart.
