What you have to be referring to are the Mini FireStorm guns...they are a Bersa Thunder (fullsize, not .380) Mini...
Great gun..the Thunder was and has been made for a LLOONGG time...its a very good Walther Copy. When the 94 ban was imposed Bersa was one of the very few companies that didnt like the idea of neutering its capacity the gun was designed around.
So instead of doing what everyother gun company did and sell the guns with Clinton mags...they stopped importing them instead. They came out with a Compact/mini instead.....
The Mini FS is a design thats been around for years...my father shot/owns/loves a Thunder fullsize 9mm forever....same gun as the smaller version.
The 45 ACP is the newest caliber and frankly, is too new to know much about it.....I dont see why it wouldnt be a very very nice little gun.
Controls are first rate...trigger is very nice, sights, ergonomics, dependability etc....are all up there with CZ,Sig bla bla bla......
Hope this helped.....If they came Cond 1 ready...Id own one.
Shoot well
