Size matters. There are advantages and disadvantages to guns of every size, shape and description. Ask James Bond; there are [tuxedo-intensive] times when only a .25-caliber mouse gun will do. Ask the pilot of the A10 Warthog; there are times when only a 30 mm GAU-8 Avenger rotary cannon will do. I’m guessing that the largest firearm/gun you’ve ever shot falls somewhere between the two. What was it? Where’d you fire it? Sexual metaphors aside, what did it feel like?
