I carry a full size Sig 1911. However, it isn't a good practice to change your weapons outfit because of one random incident. The odds of ever being in a firefight is low. The chances of engaging an armored active shooter is astronomically low. If it concerns you that much I would suggest practicing a double tap COM and then one to the head. Or even a "double-double". Practicing that is a better solution than lugging around a piece that isn't practical for you, because chances are if it's annoying you won't carry it as much, which is no good for anyone.
