Browning XS Skeet Citori, with 30" barrels, and an adj comb - is my primary gun for bird hunting, Skeet and Sporting Clays and 5 Stand. Its a lot of gun for the money these days retailing new for around $3,000. I have XS Skeet models in 12, 20, 28ga and .410 - so they meet all my needs in the field and for most clay target games. Most of my guns have close to 100,000 shells thru them / and no malfunctions...
For Trap - I turn to a Browning XT, Trap model, 32" barrels and around 10 lbs .... longer and heavier ...its a better Trap gun for me ( at singles, doubles or continental Trap). I have single barrel Trap guns / but I rarely shoot them.
My do everything well travel gun / when I only want to take one gun for a little bit of everything ... is a Benelli Super Sport semi auto. Its real light, even with a 30" barrel - but new its under $2,000 so I don't mind letting the airlines ship it for me ( where I would not give them a good O/U ...just don't trust them ) ...and insured or not / the last thing I want is to get at my vacation site and not have my gun / set up the way I want it. I think a Beretta 391 is a good alternative - if you like a gas gun / I don't. The Benelli inertia system shoots way cleaner / easier to strip and clean when I get back to my hotel for the evening or before I leave the gun club.
