I am considering the Mossberg 930 for home defense (combo) and for use at IDPA side matches. I don't really care for the tactical sights on the 930 SPX and would like the gun to be a little more versatile...The 930 HD combo comes with two barrels and it's less costly than the SPX also. My question: Any reason I wouldn't be able to add a mag extension to the 930 home defense (18 1/2" barrel)? Thanks in advance!
