I own one of these guns, and if broken in properly, they dont jam. They do however require some money, and a sholderpad for breaking in. Stoeger says 3-4 boxes of mag class shells. I found that it takes about 200 magnums run through it before it will handle the low brass loads. I will however, chalenge anyone with a SBE to outshoot my Stoeger. The Stoeger is a top-notch gun, almost any hunter can afford,that had I not won it at a hunting banquet, I would have never given the gun a thought, but I tell ya what...that gun will out-shoot almost any gun in the woods!! I like the balance even better than the red label, or the citori. Of coarse I know that they are over/unders.....but they are high class guns, that I have shot, and dont like as much as my Stoeger.
another thing....cleaning...O MY GOD cleaning it is a 5 minute chore, 'bout as hard to clean as an 870, and I can do twice as good a job cleaning my stoeger in half the time as you can ANY gas operated system.

IMHO...I'd rather have 2 Stoegers, a case of high brass shells, and money to put in my gastank than 1 SBE.
