I've never felt a "nice" trigger on a shotgun, every one I've fired has been OK to not good. Even on my buddy's TS12 it's not fantastic.
That being said, I'm not expecting match grade triggers on my shotguns so it doesnt bother me much.
Recently, I had a gentleman bring a Beretta 1301 COMP pro into the shop for a trigger job. I expected much better from a higher end shotgun. LONG take up, mushy break, and long reset.
When I took the internals apart, machining marks were still clearly visible on the working parts. After filing, polishing and fitting, I got it down to a crisp 3.5.
That being said, if I were the owner of the weapon, and I had to pay someone to get it "right," I would have second thoughts about spending that kind of money on said shotgun in the first place.
