I got this PM from fellow KTOGer and LCP guru/moderator Kraigster with a cautionalry tail on this ammo. My reply follows. Hey Rich - I can't recall any k-boom issues with that ammo although I have heard of several issues relating to QC with Magtech in general. For instance, IIRC, someone chronoed some once and got inconsistent readings ( fairly wide variances). I think I may have seen a magtech round that was undercharged or not charged and resulted in a sqibb too. Of course that can happen with just about any ammo but generally speaking, I don't think it's great stuff. I would assume that the KB was likely ammo related. Over the years, we have seen a couple in P3ATs. The design is pretty sturdy and they are not likely to blow up for no good reason. I assume that the gun channeled the energy mostly away from the shooter and hope that no one was injured as a result. In the couple of P3ATs I've seen, the blown gun perfromed/failed as designed with the over-pressured round - that is no one was really hurt. That's got to be scary as hell for the shooter. I'm sure that regardless of the cause, Ruger will replace the gun. I will pass the word of warning on the ammo. Thanks - dale Magtech Guardian Gold +P 380 - We report - you decide. :-?
