For the use you describe, don't go too light, at least 6 1/2 lbs. to smooth out dynamics. The last thing you want is a sub-6 lb. whippy, short barreled .410 for dove and clays. I would suggest a Beretta 687 Silver Pigeon II with 30" barrels if you could find one. Call Joel Etchen Guns and see if they can put one together for you. You might also check with the Beretta Galleries in Dallas and NY, they sometimes have guns regular dealers do not. Good luck in your search.
