What would you guys recomend for a semi auto shotgun thatll be used for trap shooting and upland bird hunting?

26 28 or 30

What do you mean, 26, 28, 30?

It's gonna depend on the gun you choose, how it mounts to your shoulderand how it swings when you have it mounted. A beretta will not mount and swing like a Browning which will not mount andswing like a Benelli, etc...

Try different models and barrel lengths and get what mounts and swings the most naturally.

I will say that a 30" barrel on a semi auto is a loooong barrel.

He means barrel length.

I have been shooting a Benelli Super 90 with a 21 inch barrel since 1995 and have had no trouble killing anything that flies or deer and hogs with buckshot, but I like a short barrel. My Dad had a 28 inch barrel on his Benelli but liked my shorter barrel better, so I got him a 24 inch barrel which he likes alot better.

Generally, trap guns have longer barrels, but since you are going to use the gun for upland hunting too, I would recommend a 26 inch barrel. I will admit that the longer sight plane is helpful on trap and skeet.

you can use a 28in.....but get a patternmaster choke for trap or birds...30 would also be very well as long as you once again use the right choke

Lots of companies will make an upland special shotgun, and it'll be 22" barrel, which I think is too small, so IMO, a 24" or 26" would be good choices.
