Well, I did it. I bought the Benelli M4 H2O pistol grip from an online place called, believe it or not, "Hunting Stuff". It'll be at my FFL's tomorrow. It was the best deal I could find, no C/C fees, no sales tax, and free shipping. It still almost hit 2K. I also ordered a 7 round tube/Wolff full-length spring, GG&G bolt release, and a 3/4" No spin charging handle. That's all my wallet could take before it exploded and blew off the 3 fingers of my left hand.
I was tempted by the Mesa Tactical aluminum forend but thought better of it, at least for a while. There are so many add ons that would be cool but we have to be sensible...yeah, right.
Just out of curiosity, has anyone used the Muzzle brake/comp thing? It looks kinda like a crocodile? I didn't think brakes actually did anything on shotguns except maybe shredded the wads.
I'll mainly be shooting slugs, as that's my nature, and I can cast slugs. I have a Russian ASM mold that drops what looks like a gigantic pellet with a hollow base. That baby weighs in at 617gr and cloverleafs at 75 yards out of my old Browning Auto-5. I hope it does as well in the Benelli M4.
