I'm looking to build a turkey specific gun on a benelli. It'll be a 20ga. I'm looking mainly at the m2, or SBE 3. I'm leaning m2 because I want it drilled and tapped, and heard there were issues with that regarding the SBE 3. I've also heard they now come drilled and tapped. Can anyone verify that?The shortest barrel I can find from the factory is 24". I'd prefer 20 or 22. Does anyone have any experience with cutting a benelli barrel, and how short you can go and still be able to rethread for chokes. I'm also assuming it would have to be with another thread pattern, and not the crio chokes, if it's even doable. I don't see where benelli, or anyone else offers a pistol grip stock in 20 ga. I've read where a 12ga stock will fit, but just needs sanded some at the receiver/stock junction to make it flush. Anyone with experience there? Basically, I'm trying to figure out if the juice is worth the squeeze. I'd like to end up with a finished product of a 20ga pistol grip m2 or SBE 3 with a 20"-22" barrel, and run a reflex type red dot on a scalarworks mount. Stocks will be dipped in mossy oak greenleaf, and metal cerakoted in some shade of brown. I'm open to ideas/suggestions.
