Make sure you get someone who knows what He's doing.
A couple of years ago I had a Parker Trojan that had the butt cut off at a bad angle and as the gun was in good shape I wanted a new stock put on it.
The gunsmith talked me out of it, saying he could do a butt transplant for a lot less and I would not be able to tell that it had been done.
Well I got the gun back and you could clearly see the seam where it had been rather crudely done, He told me it would never come apart and he said he had run long wooden dowels through the joint. About 3 months later I was shooting skeet and the gun came apart in my hand. I brought it back to the smith and he apologized and said he had been trying a new glue, but he would fix it forever this time and run carbon fiber rods through it.
About a month later the same thing happened, this time totally destroying the trigger guard. This time the smith was mad as hell saying he would fix it this time but it was the last time and he said I must have dropped it. Well he said he fixed it good and he claimed this time he put stainless steel rods through it. (by the way each time it broke there was no sign of rods of any kind through it).
This time it lasted a week and broke apart again. I said the hell with it and glued it up myself, this time it lasted about 6 months and broke again so I replaced the stock with one I bought on Ebay.
I will never have a stock transplant again.
