I had a Tristar sxs some years ago and after about 50 shots the safety failed causing one of the barrels(the right one I think) to fire whenever the safety was taken off. I had to have the gun stripped and some internsl parts reworked and hardened. It was a very expensive procedure. Never again.
Google the Optima Silver Select. Nice O/U for the money. They are in the $600 range. Hatsan Arms Company. My wife is shooting trap with one. They come with a bunch of chokes, nice rig! Walnut stocks on most of them are pretty nice too!
