I had a Thunder 380. I bought a Promag (1st mistake) mag for the 383. Initially it looked the same to me, but comparing them side by side the front of the Thunder mag was cut about 1/4" deeper. I filed the 383 Promag down and made it work, but it did not work well. I had to file it down to get it to lock in to the mag well of the gun. The Promag didn't work for very long before the spring started sticking down inside the mag. A Bersa factory mag might work. I have never seen one. Compare them side by side if you can. Good luck.
