Got a new Bersa Thunder 380 + and really like it. Shoots every type of factory ammo that I have tried with out a hiccup. My handloads are a different story. I average 2 light strikes per magazine. They all typically fire with a second hit, luckily the pistol is a DA/SA. I am using TulAmmo primers that I bought long ago and work fine in everything else that I load with small pistol primers. Being that these primers work in everything else I'm thinking the cup must be just a bit thick for this pistol, as I verified that the primers were fully seated during one test with the same results. My question since it looks like I'm going to have to look for some other brand of primer what brands are known for having thinner cups?
