P32 hands-down
My ancient P32 (ser # 035xx) was carried for 3 straight years and I shot about 1,000 rounds through it of almost every type with only a SINGLE malfunction. (RBCD "FTF" which I blame on the ammo) At times, I would load a mag with three totally unrelated ammo types, in an effort to make it malfunction, which it never did. I found the P32 to be easily the most technologically advanced pocket autoloader ever offered to the public at an affordable price. I'm drooling over the newly-rolled out P-3AT by Kel-Tec and expect it will be another winner. Do I sound like a fan of Kel-Tec products? You might say that!
