I've got a Tristar in 12ga, a sxs.
So far, so good.
It handles well and has decent wood on it, and the barrels seem to be regulated properly, though I have not shot paper with it. I am basing the regulation on a few shots on water at wounded ducks.
The safety and barrel selector is gritty, which someday when I get the urge, I'll take it apart and see what's up with that.
It's a single trigger, and it seems to be OK as to feel and pull weight, but I haven't checked the trigger pull with a scale.
For a sxs at about $700, I think it's OK. Not as good as my Model 470 20ga Beretta, but the Tristar doesn't cost so much either.
It is steel shot proofed and comes with 5 chokes.
