But as you say, not impossible. And it is exactly what happened to me when I ditched a HKUSPC for a Kimber UCDP. Shoot both at the same range trip and you'll see. Total and complete outperformance by a smaller gun. I've carried it ever since."Smaller, same or better caliber, lighter [&] less recoil" is a tough combination to come up with. Not impossible, but difficult. A smaller, lighter gun in the same caliber as a larger, heavier one, tends to result in more recoil.
