Rusty:
Respectfully, you do know that the 3rd generation Smiths have been discontinued by S&W altogether, right?
And if you understand that I'm sure you understand that there are still thousands of NIB 3rd gen. Smiths available at gun shops all over the place as well as several on line dealers, of which CDNN is just one?
A NIB discontinued 3913 (such as I purchased from CDNN recently) comes with a lifetime warranty, and if you have any experience at all with these pistols you should know chances are excellent any NIB 3rd generation S&W pistol you buy today will probably still be in excellent condition when your heirs are shooting it decades from now?
And I don't know what that "9mm NATO" business is all about. The Smiths shoot the old standard 9mm (9X19) ammo available all over the place, and in fact is the most popular centerfire caliber & cartridge in the world.
I'm certainly not knocking the other manufacturers you mentioned as I've owned a 9mm Glock, Sig, and HK.. I don't care for the Ruger centerfire pistols, but that's just personal preference, but none of them are any better, or will last any longer, or will perform a role as a self defense firearm better than the 3rd gen Smiths.
If a person prefers plastic over steel, or has a preference for another brand of firearm I have no problem with that but I guarantee you if you care to research (or google) 3rd gen Smiths in general and the excellent 3913 series in particular you will find they have a very good, well deserved reputation and are considered by many knowledgeable in the firearms industry as the high water mark for S&W pistols.
Just personal opinion, no offense..
Best Wishes,
Jesse
