Typical steel 31⁄2-inch shells are 13⁄8-oz. The 23⁄4-inch “baby magnum” lead shotshell has always had a 11⁄2-oz. The preconceived notion is that a 31⁄2-inch shell is automatically a Roman candle-but that is far from the truth. Whether a 31⁄2-inch 12 gauge makes a lot of sense today is another matter. Thats not quite obsolete, but Federal Cartridge currently lists only five 10-gauge loads, while the company offers more than 75 different 12-gauge shotshells. It was the Mossberg 835 slide-action that helped launch it, and it was the proliferation of the long shell that sealed the demise of the 10-gauge shotgun, as you can actually get more performance out of a 12-gauge 31⁄2-inch load, chambering it in a shotgun that is less bulky, more versatile, and less costly to shoot than a comparable 10-gauge gun. Mine has the early rifle sights, so a rare-bird this one will be.Somewhere in the neighborhood of 1988, the last “new” production shotshell cartridge of any note was introduced by Federal Cartridge Company: the 31⁄2-inch 12 gauge. I did see that Benelli does now sell this shotgun to LE in this configuration, so you can find them on Gunbroker - but they are the ones with the ghost ring sights. My recoil tube should arrive tomorrow or Tuesday and if that's the right one, I should be good to go. The grip only needed minor modifications to get it to allow the rear end of the trigger guard to fit inside it, as the trigger guard extends about 3/4" past the end of the receiver. A heat gun for 3 minutes and a screwdriver to get some leverage in the drain hole at the end to twist it off and it worked. There isn't much info online about the M3 and this modification, but I read about removing the 'dummy' recoil tubes on Benelli's and was prepared for a battle. I did have to modify the inside of the pistol grip a bit so that it will fit flush against the rear of the receiver. Since mine is a very early M3, I gambled and bought this one:
