Throw the Ruger SR9 into the mix and I think you have a winner.
You can buy, sell and trade guns for twenty years and still be looking for the "perfect gun". It doesn't exist.
Some you will love, some you will hate and some will have you beating your head against the wall wondering what you where thinking when you bought it.
As a resident of Illinois, are you in a town that "allows" handguns? There are many patchwork towns and each has its own ordinances on guns!
I lived in Evanston and I was not allowed to own a handgun. I could own a rifle though! Strange when you think about it as a long gun is far more deadly than a handgun!
Just one last thought and I'm gone... I'm glad you didn't ask about calibers!
