The Star Firestar is a nice gun, and the trigger can be easily gunsmithed to be outstanding -- as I found with two of them.
But the gun is HEAVY!!
One of the jokes at the range where I shoot was that if I ever had to use the gun in self-defense, and missed the bad guy, all I had to do was drop it on his foot -- and he'd be out of action for weeks.
In fact, the gun was so heavy I couldn't practically use it as a concealed carry weapon -- it just drug down my pants, regardless of belt or holster.
But there are good alternative: until recently, I carried a Star Firestar PLUS as my CCW. Same top end, but with a much lighter alloy frame, double-stack grip, and up to 13 rounds, rather than the standard 7-8. (The .40 version of the gun has a 10-round mag that can be used in the 9mm without modification; it is identical to the much more expensive 13-round hi-cap mag. But its hard to find the .40 mags; they are around.)
If you plan to shoot it ONLY at the range or use it for home defense, there are a lot worse guns for the money.
If you think you might have to carry concealed, check out the Star Firestar Plus. (I retired my Kel-Tec P-11 when I found the Firestar Plus; a bit heavier than the kel-Tec, but almost the same size. And a much, much better trigger.)
I've since moved up to a CZ-75B Compact. Very nice, small gun, a bit easier to conceal, and the one I've got is a real tack driver.
