...fwiw, i had the hardest time trying to fit an extra set of .20 gauge barrels to my 9.3...a one year wait and two barrels later, the shotgun barrels still misfire on certain ammo...what's worse, given the euro-style rifle stock (which works perfectly on the 9.3), it is nearly impossible to aim the shotgun bead without brusing your cheek...will keep everything 'separate' the next go around...
