i don' t use shotguns that much any more and my 870 serves me well when i need to use a shotgun but if had to do a lot of shooting in one or several days like you describe i would definately get a beretta 391, i wouldn' t hesitate a second. i worked part time at a sporting clays range in the summer and fall of 2001, and the 391' s ruled the roost out there whether it was with the regulars or with folks from around the state who came to shoot in the tournaments. most of the people out there took the sport seriously and had a lot of money wrapped up in it besides their shotguns, which means that they weren' t going to use anything cheap or unreliable. my observations were that the 391' s have a lot less trouble than any other shotgun out there. i also cleaned the rental guns (391' s) and those things would take a pounding before they started having any troubles with malfunctioning due to being dirty. i talked to a lot of the regulars and they go on trips similar to the one that you are going on and the majority of them were taking 391' s as their primary shotgun and probably another 391 as a backup. there' s quite a few really good semi' s out there, pick the one that fits you and your budget best. for me it would be the 391.
