One of the first steps in gunfitting is to develop a consistent and repeatable gun mount.

Here is where gunfitting and to less extent the clothes worn need consideration.

I have performed gunfittings for shotgun brands such as Purdey, Perazzi, Beretta, Caesar Guerini, Blaser, Krieghoff, Grulla, and probably a couple of others I can't remember.

No damage whatever was done to the interior of the turret or to any of the gunfittings or their slides.
