red:
My P-13 was the first "real" handgun I bought (I spent "real" money on it). It's one of my favorite handguns. Trijicon sights, Hogue grips, a Wilson guide rod, and a beavertail grip safety are the additions I made to mine.
I would watch magazine springs/followers. These are the weak link in my experience, as far as feeding/reliability are concerned.
I bought the pistol originally to carry, and decided it was too heavy and bulky. For accuracy, speed, and shooting confidence, though, it's still my baby.
