I can never get great details on the XTP's performance. The only thing I can find is that it is a very consistent bullet in both expansion and penetration. What is the street credit for the XTP? Since the XTP is known for penetration, how well suited is it for CCW? These rounds intrigue me with their feed profile similar to that of an FMJ round, great accuracy, and their consistent performance. I just never hear about them involved in a lot of testing, especially in .40 S&W. The best I can get is "I carry the XXX grain XTP." That's great, but why do you carry it? What made you decide to? 155 grain or 180 grain? Thanks for any help in my search of XTP information.
