When I first started to carry my 9mm I just went out and bought the cheapest self defense ammo I could find which was the federal hollow point. After some thought I decided i shouldn't short change my safety. So I bought a box of Speer Gold Dot after reading a few forums about ammo. Then recently I bought a sig 238 shooting the .380 and I wasn't thinking and I bought a box of the federal hollow point again. But with that ammo I was having a problem getting the gun to chamber a round so I went back to the dealer I bought the gun from and they recommended I get the Hornady Critical Defense. Even with that I was having problems getting my rounds to chamber. But then I learned there was a malfunction with the operator that problem was easily remedied. I'm curious what brands everyone is using and why? Do you prefer a higher grain or a lower grain for your self defense needs, and again why?
