Okay so I've decided i wanna beef up my Maverick 88 by givin it a few things. Im looking at a heat shield, pistol grip with solid stock. and a pistolgrip forend. but as i've read no one makes them so id have to switch out the 88 barrel and mag for a 590 or a 500 and then i can get the grip. Would all that be worth it and about what price range am i looking at? from just glancing i see about 100 in just accessories not the barrel change out and the forend grip.
