I'm a lefty shooter and have mainly shot skeet over the years with a Remington 1187 with 28" barrels. Our club also has single trap so I tried it out recently with the 1187 and am liking it a lot, I already have my average to about a 23 after only a dozen or so rounds. I'm on the hunt for a dedicated trap gun, I had been looking at BT-99's which I've heard are pretty much neutral cast then I stumbled upon a practically new (30 shells shot) Beretta 687 Joel Etchen silver pigeon III, its a 30" O/U, adjustable comb/pad and priced pretty well considering its practically new. I like its cast for a LH shooter and adjustable for shooting trap. The only thing I don't like is the fact that all we have is singles and no double trap in the area so the O/U barrel will be mainly used as a single shot. Will using a 30" barrel over a 34" single barrel but much of a detriment?
