Great choice! I love my SLP. Mine is the standard MK1 model. It is my do it all shotgun.
I recomend going to Midwayusa and picking up the Browning sporting clays piston (Item # 493004) for it. It is rated for 1 1/8oz and lighter loads. Just to round out the two that come with it. Maybe a set of Invector chokes too. Check out the Trulock Tactical choke (Item#857120) I havent bought it yet but it looks really cool.
