I really like the 3rd Generation 9x19 S&W guns, but logistics make it a struggle to use them seriously. My daughter is a huge fan, carrying a 3913 and using a 3906 as a HD pistol. My wife has a 3914 she likes. But logistics continue to get harder. Even the Xenoy grips and magazines have become hard to find. Many of the parts are no longer available, and S&W has all but dropped factory servicing of the guns. I have learned that the best and least expensive way to get spare parts is to buy spare guns as the various firing control parts are really sets (example: do not use MIM sear with forged hammer as the sear nose geometry is not identical). Used samples can still be found for about $300-$400, which is much less expensive than buying just a slide and a barrel.
