I am totally new to shotguns. Went with a friend today and shot his 870 Express Mag at some clays. I absolutely had a BLAST! Now I HAVE to buy one. I would like for this to also be a HD shotty as well. I am having trouble deciding between a semi and pump. So far in the pumps I've looked at the 870P, 870 Express Tactical, 887 Nitro Mag tactical, Mossy 500 and 590. Any others I should look at? For the semi's: 11-87P, 1100 Tac4 and the Mossberg 930 SPX. Any others? I would really like to keep this under $1000. As I stated, I'm new to these and not sure really what to look at or what I really NEED. Any direction is greatly appreciated!
