Oh yeah, if you want to spend a little less $$ and start off with a good used gun, I have a Mossberg 500 in good shape that I'll send ya for $225.00. I would need a copy of an FFL's license to ship it to. Any arrangement you make with him is another issue.

Also, don't believe that line about not needing interchangeable barrels. You definitely want the flexibility of changing barrels. The 870 and 500 probably have more barrel options than any other pumps on the market.
