I am one of those gifted people who can shoot any gun well, regardless of barrel, choke, stock combo, number if triggers, until I buy it. Then the fit goes away and the misses begin and I like it that way. Who wants to hit everything you shoot at? Limits are too low and a few misses makes a hunt last longer.
I have been fit multiple times. For clays, once for a side by side, a O/U, pump guns and once again for clays about 20 years after the first fitting. Everything is different and there was very little common ground between the measurements. I did learn how to compensate and adjust better for minor gun stock differences. Every fitter has his particular "special" aspect which he thinks is the magic answer to our misses. One worries about cast off, cast on, another worries about toe in or out or negative or positive this or that, longer this or shorter that. They are all right and all wrong at the same time. At best they can get you into a fairly generic fit and you need to refine it from there. Practice will show you what works and what does not over time and the more you shoot the more your needs will change.
I learned it is all about feel and adjusting until a gun just feels right and shoots where you want it to. Gain 25 pounds, change layers of clothes, get 10 years older, work behind a younger, more aggressive dog, go from a sticky pad to a smoother or slicker pad and it changes everything. Do not even think about bifocals and gun fit.
If you think you need 16" lop try it for six months. At one time I shot 7/8" drop at comb and now shoot from 1 3/8 to 1 5/8. Gain 50 pounds, get older, change from pre-mounted to low gun or semi low gun and your needs will change. To me fit is just another reason to have more guns.
