i do not know the ballistics for it but i will tell you this is a great little gun. i carry one with an extra mag everywhere i go. i have heard that for the .380 caliber, cor-bon has the best ballistics though i do not know what they are. i shoot a box of these about once a month to keep them from getting too old and to make sure they cycle well. have not had a jam yet.
what kind of shotgun did you trade for 4 very fine pistols?
