Just over seven years ago when I bought my first SD gun, I was originally advised that I should only use American made, brand named, brass cased ammo. I must admit, that until this past week, I was doing an ammo inventory and insuring that I was rotating stock, did I realize that the off and on again stock of Magtech ammo I had was made in Brazil. Never had one problem with it in either my .380, 9mm or my seldom used 70 year old 1911A1 Colt. Needless to say, it will be one of the exceptions to the rule.
