I was out in the backyard today doing a little target practice when my 380+ did something it had not before... it did not fire. I've run several hundred rounds through it since I got it, Winchester, Remington, Hornady, Blazer, and, if memory serves, some Tula. Today it fired 2 or 3 rounds of Tula 91 grain (the green casings) and not fire again. I reloaded with Remington and still no fire. Any ideas? Could the Tula have caused something to break? Everything looks okay, but I'm no gunsmith.
