I keep seeing comments along the lines of: “Instead of telling women to carry guns, teach men not to rape.” Why should the two measures be exclusive of each other? The same applies to self-defense at home: 911 on the phone is great, but not to the exclusion of more immediate measures.
And, while not for defense, American Eagle Synthech 115gr polymer -coated ball is pretty good ammo. With higher velocity produced by the carbine barrel, reduced friction relative to copper jacket is a plus.
