The only reason I bought my 220 was because I already had a few 1911s (too pretty to carry on a daily basis) and wanted a 45 I could bang around. That said, a few years later I picked up a TacOps as well. It's a win win situation, either gun is a great choice.
The only time you can have too much ammunition is if you're swimming or on fire!
Gun stores: Where the morbidly obese can pretend to be mercenaries, allude to past experiences in Special Ops, and overuse words like "tactical" and "piece of kit".
