The Firestorms, either the Argentinian ones, or the new Phillipine made ones, have not had a great rep. I have not owned one of the Firestorm models, but have examined, shot, and not been impressed really with any of the Phillipine makes. They tend to be a little loose, grips don't interchange (most other parts do, though), and I believe the frames are cast. There are OK cast frames out there - like the investment casting Caspian does, but these aren't up to that level.
I have done the 1911 thing from a box-new Norinco up to very custom-built models. After lots of experience, my advice on an affordable 1911 to a buyer trying to fit a tight budget is this:
Buy a used, well-made gun, avoid retail. Colt Series 70, S&W, Springer, etc. Another way to go is professional gunsmith-built custom job on Caspian components. These can be had for often less than 50 cents on the dollar used. Pawn shops, gun shops, and Gunbroker are your friends. Anyway, the point is that quality counts in the long-term and you want forged steel that is tightly machined and well-assembled. You will save money in the long term buy purchasing a solid build for a $100 or $200 more than you want to pay, and not end up modifying/altering a lesser gun, or trying to get it to run properly with various ammo with throat jobs, etc.
My two cents, but maybe it will help.
