I think gun fit is somewhat over rated. In an ideal world, every gun would fit perfectly. In the real world, humans are extremely adaptable. Find a gun that is close to what you need and learn to shoot it. When I was a kid, the old guys who didn't miss much had never had a gun fitting. They would have fallen over laughing if someone had suggested they get their old pump guns professionally fitted.

I will concede that if you are a competitive target shooter, fitting has more value.
