My experience with attempting to bend stocks is exactly what this guy says:

The Spanish gun and a Scottish gun I had done all returned to exactly where they started. A friend’s gun has been bent multiple times, and is right back where it started. It is an unfortunate fact of life that guns will need to be altered for some individuals, but, in the great majority of cases attempting to bend stocks is absolutely not the correct way to do it.

If you have a moment, continue on in the blog to the rebuilding of the Boss single trigger. This level of gun making is seldom encountered outside the shops of one of the big three. Master work.

Best,
