You might adjust to any gun but you'll never shoot as good as you can with one that doesn't fit.
I'm going to have one bent currently it's 1 & 7/8" and 3".
My friend says he can get an inch with a straight stock and less with a pistol grip.

I'll let you know how much he bends it. I'm hoping for 1 & 5/8" and 2". The gun has a sleak flowing pistol grip. Hopefully I'll have the results by next week.
