We just got back from getting the wife's Thunder 380. We also picked up a box of Remington UMC ball, and Blazer Brass ball. I trust these run ok with the Thunder 380? I should have checked in prior, but they gave us a little discount on the spot seeing how we also bought the pistol. While there I also picked up a SCCY 9mm (Gen. 2) for myself. I was going to get a Thunder 380 as well but my wife's was their last one. But, they gave me a good deal on the SCCY so I went with it Today was a great day to celebrate Gun Appreciation Day for us.
