I have a Firestar Plus in 9mm. It is a FINE little pistol. It holds 13 +1 rounds of 9mm. I have several magazines for it but two hi-caps is all you really need.
It has been a reliable, accurate pistol with many rounds of full power loads through it - factory and reloads; lead and jacketed bullets; round nose and hollow points - digesting them all without a hiccup.
The trigger is a bit rough but has improved greatly with use. It has not hindered function, reliability or practical accuracy.
I bought a nice holster and spare magazine carrier for them from Brigade Gun Leather.
In my opinion, the stainless models look nicer than the blued if that's important to her. Mine's black.
My recommendation, without reservation - BUY!
Please remember, my comments above are based upon my use of my Firestar PLUS, not a Firestar.
