All,
The Benelli issue is not so much of a cracking issue. PJR, the problem is a warping issue due to the aluminum receiver. This is more likely in any aluminum framed SG. As far as the level of abuse necessary to cause this problem, apparently its not as much as one might think. Sure, any gun can be destroyed. Give me any long arm or HG and a brick wall and I'll show you two halves of a long arm and quite possibly a pile of parts in the case of most HGs.
Let me say this, take a Benelli Super 90 M3 and a Remington 11-87 or 870. Stand about 10' from a pine tree with heavy bark and hold the SG at each end and toss it with moderate force against the tree 3 times. Don't slam it, just toss it as though you're tossing a basket ball to a friend after a game. I'm confident a Remington with its steel receiver will continue to function. I have no confidence the Benelli will. This of course is my opinion and speculation based upon what those who are in a position to know have said.
As far as the 11-87's "weak" o-ring issue. How many of you have needed to replace one or have known anyone to have one replaced due to failure? After how many rounds? I know of not a single case where one had to be replaced due to failure. This is not to say that I wouldn't replace it periodically as a precaution, or at least have a few on hand.
Understand, I'm not suggesting all Non-Remingtons are junk, but I do believe that as of right now, Rem's. are the toughest available. I must side with Will Beararms any gun will wear out. I've worn out my first Sig P-226.
Danny 45, you're right, Winchester's SGs are pure unadulterated BS. I had one around 12 years ago and had nothing but problems w/ it. I've seen NO model or quality changes in Winnies since then. What ever happened to the Winchester 1897? Too expensive to manufacture they say. I say bull, charge what they must. That 1897 was probably the best all-around SG ever designed. I have my grandfather's original. What a gun...
P.S.
PJR, one last question. Benellis dont need to be regularly cleaned? Does this hold true if you continue to use it in the semi-auto mode or just the pump mode? (Assuming as S90 M3). I haven't "regularly" cleaned my 11-87, but it does need cleaning after a few trips to the range/field. In my experience any firearm does. Don't get me wrong I don't hate Benellis. Sure, they look bad-ass, I just wouldn't choose one for anything more than hunting.
