Try the Benelli forums - Stoeger is now a subsidiary of Benelli. This has some perks, as Benelli put InertiaDrive into every gun they make - from mainline Benelli, to Franchi and now Stoeger. The original Stoeger 2000 was a historically problematic shotgun, which is slowly now coming to its own under Benelli. I hate guns that require a "break-in period" to function properly, but this seems to be the case with the 2000 and owners who deal with it, ultimately love them - especially for the money. Accessories are few and far between, though I do believe the receiver is tapped for either Remington or Mossberg, (I can't remember now)....
