I have a Benelli M1 Super 90 18" barrel, full length mag tube, and ghost ring sights... that has had at least 250 shells ranging from 3" magnum slugs to reduced recoil buck shot, to practice with low brass #8 bird shot, and that gun has never even thought about malfunctioning. Of course, my gun, like all of my firearms, is cleaned spotlessly after every use.
I don't even know what the "click" is... something tells me it might be the sound you hear when you squeeze the trigger on a bolt that isn't fully closed, but I always let the gun work the way it was designed to -- I let the bolt go and let the recoil spring do the job it was designed to do.
I love my Benelli and there isn't a shotgun out there I would trade it for. The Ferrari of shot guns.
