I have had several fittings. I needed to revisit the fitting as I got older and larger. Also I found that not all fittings are created equal. Fittings can vary from vague to anal retentive. If they are not taking the time to have you shoot the gun you are wasting your time. POI is a very important part of the fitting process. After all we are bien fit to hit what we are shooting. Mounting a gun is not shooting a gun. Most of us can not get a true fitting just by mounting a gun.
Another thing to look at is the style of shooting and how it will change your fitting needs. A pre-mounted gun and a low gun shooting style are not the same for me in gun fitting. Figure out what style of shooting you are interested in and find someone who understands that style of shooting. A Skeet or Trap expert fitting you for a pre-mounted, high gun style will give you different measurements than a fitter who is looking for a hunting, low gun style. In my case the comb was almost 7/16" difference. So I can not take my clay target guns hunting and have a well fitting gun. While I can shoot my clays guns at Skeet or Trap the lower and shorter stock on my hunting gun seems to invite lifting my head with a missed target the result.
My wife says this is just another excuse to buy more guns. She is right but I tell her the numbers are different and you can not ignore the numbers.
