Anhinga,
Two different worlds. I just sold my second P-11. It doesn't matter how much you tinker with the trigger or dry fire it. Or if you fluff and buff the P-11 it will NEVER be in the same league as an M&P 9c. The P-11 is lighter but the quality is nowhere near the Smith. The P-11 is only marginally smaller. I can shoot my M&P 9c all day long. Anything over 100 rounds thru a P-11 is truely a painful experience. Ask yourself, why am I buying the pistol? What is your need? Isn't your well-being worth the extra cash? Save your sheckles and buy only quality!
Just my opinion. Take it for what it's worth. Besides the KT P3AT, which fills a concealment need/niche, I will not purchase another Kel-Tec.
PS. I also sold my G26 and G29. I really really like my M&P.
