Sweet! I used an 870 for a long time and still keep it as my spare gun. Picked up a used Browning Citori O/U this summer for trap and skeet. It's not nearly as nice as the $2500+ guns most of the guys use, but it's been a lot of fun so far for $1000!
For some reason I like the pump the best. O/U and semi's didn't make it enough of a challenge with having to cycle the round in time to get the second clay.. One day I'll pick up a nicer shotgun.
