Yeah, I'm figuring 18.5" barrel.
But am I allowed to cut it off myself? I know that the actual muzzle has a major impact on accuracy, but I'd be firing shot shells at short range, not a slug at range. (Though I
do realize that even with a short barrel, there's not much spread at bedroom range!)
I'm not too concerned about getting a safety off. Although I haven't done much with firearms lately, I went to Nationals in college for Rifle, and I taught riflery class at a major university, so I'm comfortable with longarms and safeties.
Interesting points about the "firearms" vs "shotguns"...and "Any Other Weapon".
That Serbu Shorty looks like what I'd need, though I admit firing that after just awaking might have it fly back over my shoulder!
