Apart from fitting, most shooters, at some time, will damage their stocks. Re stocking a gun, unless there are stocks available from the manufacturer is very expensive, so I always repair wherever possible and it is quite surprising, with modern adhesives how badly a stock can be broken and yet safely repaired.
Photos of a project to restore the woodwork of an English sidelock can be found in the Project Gallery

The above picture shows a sidelock stock which was snapped through the grip/hand. It has been bored from the head, through the grip, to bridge the break.

Another view of the hardwood pin, inserted into the stock, then inlet to accept the action.

The finished job, re chequered over the break and locally re finished.
A new stock for this gun would have cost between £1500 to £2000, depending on the quality of the wood. This repair was considerably less.
Approx 90% less!!!!!!

BEFORE
This is the stock and action of a Beretta SO6, recently arrived for repair. I don’t know if it was dropped, or stood on, or even the result of repeatedly slamming the gun shut, as it came to me via Chris Potters.
AND AFTER
That’s better. Once again, a replacement stock would have cost well over £1000.
It goes to show, however bad the break, I can usually put it back together again.
