Well why is that h.k besides the only place to shoot it is the range.
Because the bottom line is who give a hairy about 4 extra inches(that's what she said) for the ultimate freedom of all of the obvious benefits of having a non restricted gun.
Especially a shotgun. I feel buying a restricted shotty is throwing money out the window especially on resale(which you won't ever want to anyways).
As said above, good luck either way, you will be happy, but man for identical money the non res wins 1,000,000,000,000,000,000,000,000/1,000,000,000,000,000,000,000,000
If res was 1000 and non was 2400 and you were only ever going to a range for sure ever, then sure.
