First, I LOVE 3rd Generation Smiths..
I consider that the 3rd gen Smiths as an OVERALL package are a wonderful choice for a self defense 9mm pistol.. Reliability in spades, self defense accurate, built like a Mack truck, quality and value, hard to beat for the money.
Having said that I have never had a 3rd gen Smith 9mm pistol that was as accurate, right out of the box, as my Glock 26's, Sig P239, Walther P99's, even my Bersa Thunder 9/uc, and not nearly as accurate as my HK P7....
Or, as a dedicated "range" gun,a 3rd gen Smith would not be my first choice..
I've heard you can improve the accuracy of a 3rd gen Smith with a barrel recrown job, but since my 3rd gen Smiths are more than adequate for self defense, at self defense range, I never bothered..
I like my Smiths to the extent my CS9 finds it's way into my FIST Kydex IWB holster a lot of the time when I'm carrying a 9mm pistol, but it's not there because it's awesomely accurate... It's there because it's awesomely RELIABLE, TDA, sufficiently accurate for self defense, and I like the way it feels in my hands.
I hear CZ's are very accurate, though that's one brand I have no personal experience with.
Hopefully you will be able to shoot a example of whatever pistols you narrow your final choice down to.
Just personal opinion,
Jesse
