I'll be intellectually honest and admit I have periodically been a trade-a-holic. The one I probably regret parting with the most would be a Kimber 4" series I (no shwartz safety crap) compact with stainless slide/aluminum frame. Not the smartest move I ever made. Not necessarily impossible to replace but much harder and more expensive than say a Glock. For some of us the learning curve is a painful journey.
