I 100% reccomend the birdshead raptor grip. I also have a stocked Benelli, so I have both setups. I have a raptor grip on my Mossberg cruiser, and I love it!!!! Just practice with it, and you will hit whatever you point at... well I do anyways.. I have no issues pointing and shooting and hitting a 6" object from 15-20 feet. The beautiful thing is the difference between a pistol grip and this grip. It's very natural and when firing you get this natural swing action, that prevents to grip from slammning into the web of your hand, and also lacks recoil. Alos the tang safety is easily accesible with the grip. I like going to my moms property and leveling 1-2 ft ant hills with it! It also is easier to clear rooms with the shorter length. You will be very happy with this setup! Do it!!!
I have a TLR-1, GG&G mount, 3G 7 round card side saddle, Choate ext, and don't forget that breacher muzzle can shear grabby hands, and knock the stupid off of faces!
