That's why I'm building with 48" barrels now instead of 44" ones! As I'm getting older, I know I'll need longer barrels than that.
I can adjust the sights on the barrel, but having to dig a hole to set the butt in for loading every time I want to go out and shoot gets dang tiring.
Finding blanks for longer barrels isn't easy either. The wood under the MC can be spliced and not show, (so there's an inch or so you can fudge with) but behind that it really should be a continuous piece.
