I do believe that Firestorm is the merger of Llama and Bersa.
If Llama's handguns are any indication of what to expect out of Firestorms 1911s, I can tell you that I am content with my Mini-Max .45acp for the most part. More accurate than a $259 NIB 1911 has any right to be, and never a malfunction from the 300+ rounds put through it.
However, mine does have a nasty habit of ejecting the spent shells directly rearward, some zoning in on my forehead (an ejector problem, most likely a quick fix). Also, mine exhibits heavy machine tool marks inside, but as far as I can tell, it is strictly cosmetic, having no effect on the function.
Overall, I believe Llama to be good deal from my personal experience. Some may tell you otherwise, as it's a hit and miss type scenario. Perhaps info from other Llama or Bersa owners can shed some additional light on your search.
Good luck.
