Hey pea,

Congratulations on taking up a way of life that will enrich you beyond words. Unless your absolutely set on an auto-shotgun, I would consider the remington 870-pump--probably THE most popular gun ever made--you'll never have a problem with it jamming, ever(even if you've just pulled it out of a 3 ft mudhole) unlike the possibility with an auto. Also, for all practical purposes,you can shoot just as fast with it (remember, the 1st shot is the one that counts the most any way)
good luck
