Looks like a Colt Mustang, except the slide lock and safety notches on the slide are different. The backstrap is also different. It's also sort of reminiscent of a Colt .380 Govt model, but with a shorter grip. So what is it? The barrel looks like it was wire-wheeled to death!
I'm not 100% for certain but I believe EAA imported the FIE pistols with a "Titan" moniker. They used to sell them at Hart's department stores. (Heck, I remember back in the 80's when they carried FIE Spectre 9mm's right beside them, cheap too!) Anyway, if Numrich doesn't have the mags you should try http://www.jocoemprise.com/ , he has some listed.
