Since you asked for my opinion I would say no. My reason back then for picking up the .40 was I wanted a carry gun that I could also practice with. This was durring the great ammo shortage of (insert year) and 9mm was impossible to find and my LGS had skids of .40 sitting around. My primer supply was dwindling down and I could forecast running out in several weeks. I picked up the .40 to fill a need at that time in my life based upon my situation. The upside was that I could continue to shoot (granted it was a less than ideal setup IMO) and I had to learn better recoil management based on my physical size. If I had a choice I would have gone a different route but I did not. I found the silver lining in the cloud of my experience. Another upside is that I have another option if that situation should happen again. But I am more inclined to stick with one gun if given a chance.
