Stock fit is certainly important, but too often the fit of guns that can be "stocked to fit" are presented as if they only offer one set of dimensions.

The Merkels you find will have one set of dimensions (they charge about $1300 extra for custom dimensions.)

Chapuis will stock the gun to fit.

HEYM will stock the gun to fit.

The most important thing is to know what dimensions you need and you can specify them when ordering a gun to fit YOU.
