I bought the TT15 Combo. I had a problem with light strikes with the Unsingle. I sent the gun back to Kansas City twice and had the gun “fixed”. The 3rd time I sent it back for light strikes they said I had “Barrel Separation”. Unfortunately, the warranty had expired. I’ll never buy another Tristar.
The TT15 did not work out for me. I shot it high and to the left no matter how I adjusted the shotgun, and it is super adjustable. I still shot it high and to the left, and so did all of my shooting buddies. There was something wrong with it. I sent it back to TriStar and when they returned it they said nothing was wrong with it. They even sent a target that they had supposedly shot at 25 yards showing a nice even pattern, but the target had a hole where the wad had went through the paper, which of course is not going to happen at 25 yards. Maybe 10 yards. So they lied about that. What saved me was the fact that I had bought it through Davidson's Gallery Of Guns, and they have their own warranty. So I sent it back to Davidson's next and they sent it back to the same TriStar facility where I had sent it. But this time that facility sent it to another state for repairs. When it came back it was shooting straight at point of aim. But in my mind I shouldn't have had to go through all of that deception and lies. So I sold it and will never ever buy a TriStar again. Not ever!!!!. Had I not bought that gun through Davidson's I would have been stuck with it.
