I bought my first gun yest for my birthday ( whoohoo for me) an M2 tactical shotgun with the 2 shot extention and pistol grip and ghost ring sights for $970, well I wanted to pick up the standard stock, wasnt sure if the comfortech actually worked or if theres a cheaper one and then how to take off the pistol grip and add on the standard. and does anyone know if theres a benelli site that sells the acesseries online? I dont feel like driving an hour again to buy the add on's. Thanks for anyones help
