I am looking at getting a 20 gauge pump shotgun for the kids to use. I would have to be steel shot compatable. I am looking at a JC Higgins M21, w/a poly choke (the price winner at $175, and not sure if that is bottom dollar), a Mossberg w/a factory camo paint job, the shortest bbl (i'm thinking that is a good thing for a good for a kid), and a 870. The 870 and Mossberg both have screw in chokes and are at about $250.

I'm thinking that I've read that the polychoke was not really all that adjustable, as the pattern on some settings suffered...dat tru?

Would the PC work w/steel shot?

How durable are the Mossbergs?
