I have more (metal framed) hammer fired Smith & Wesson semi-automatic pistols than anything else and I enjoy them very, very much. Most of them are DA/SA designs and it's extremely rare that I ever take a long double-action first shot with any of them. For me, they just seem to intrigue me... I have 1st, 2nd and 3rd Generation pistols and I pretty much love all of them.
But my absolute passion in firearms are the slick five-inch full target Smith & Wesson Performance Center Limited pistols. The 952, the PPC-9, the 845, the 945. It took me 25+ years of handgunning before my wild, shocking discovery of the handguns that I absolutely love beyond all others -- past, present and future.
I also wholly consider the legendary Smith & Wesson Model 52 to be a Performance Center Limited pistol... just that it was conceived, designed, created, hand-crafted and shipped before the Performance Center ever existed. It is because of the Model 52 that the idea for the PC was even hatched.
