TriStar Arms added a number of new personal defense and target shooting handguns for 2013. I am not terribly familiar with the TriStar line of firearms, but according to the company, they only recently got into the handgun market when they introduced their first pistols in 2012.
The new TriStar pistols are chambered in 9mm and .40 S&W and come in a variety of finishes and sizes. Two of the pistols, the TP semi-auto handguns, are polymer framed guns. The other pistols are traditional metal framed handguns.
