When my son grew out of his 20 gauge last year, we went shopping for a 12 gauge. He liked the fit & feel of the SX4 and purchased it. The gun jams about every 5th shot. I thoroughly cleaned it and it still jams. I am going to get my buddy to tear it all the way apart and clean it and see what happens. If this doesn't fix the problem, I am not sure whether to send it back to Winchester or get rid of it and buy a Franchi or Benelli. We went to the gun store yesterday and he really liked the way the Franchi & M2 felt to him. He picked up the Barettas but they felt awkward and heavier that the other two. Anyone else have problems with their SX4 jamming? I think he got a lemon.
