Like i said above, my 597M has "never" jammed! Not even once. I think i'll put it on EBAY and get "rich", as i have the only one that doesn't jam!!! :>
You guys that complain about the 597's jamming, how accurate are they???
Mine shoots more than acceptable for my needs. I've shot quite a few pest around the farm with it, and keeps on doing it's job without complaint!
