I would not worry.Shoot good quality new ammo only with factory barrel you should have no problem.
I shoot reloads in mine although what I posted was not supposed to have been a reload but new. Some say the KSP ammo was hot rodded, don't know.
I just went with the KKM barrels you cannot beat their accuracy and just for my own personal confidence the fully supported chambers because of what had happen to me previously.
