Thanks!! I replaced the action spring and the recoil spring, and I reload 12g so between that and the friction rings hopefully I'll be able to dial this in for comfortable shooting - I've heard from some people that this is a heavy recoiling gun, but the literature (and other people's anecdotes) seem to say that the action reduces recoil. I guess I'll find out.
I've looked at putting an 11 standard mag tube and fore end on this, but I haven't found the right deal - I'd also like an 18" barrel for it. I've been scouring Ebay etc, one day those parts will align with my wallet and I'll have a little more capacity - 3 isn't exactly compelling for an auto loader, and I don't think the mag extensions that fit the standard model 11 will fit this fore end - the cap assembly is a little different than a standard magazine, it is threaded for a cap with a bolt running through it, rather than a cap with threads around the perimeter. I'm comfortable with my dremel skills but I'd rather not make too many permanent changes to this magazine just because it is in such great shape now. I found a 16g locally that's not terribly priced, maybe I'll just go that route for a 5+ round auto...Anyone have any compelling ideas for increasing capacity on these?
