I just read info on another list (KTOG) that MagSafe ammo has blown up two of the KT 380 pistols and MagSafe has put stickers on their ammo not to use in P-3AT KelTec pistols. I just removed the MagSafe ammo from my P-3AT and will now use something else. I am glad I had not tested this ammo only because the weather here has been too cold.
