Great video and awesome series. The pistols and shotgun are mostly used to juggle enemies in the air and/or keep your style meter up when not immediately near enemies to attack with melee, so that's why they don't deal a ton of damage. The higher and longer you keep your style meter up, the more red orbs you'll get. DMC 2 is pretty bad, but at least pretty short if memory serves. DMC 3 is probably the best in the series. DMC 4 is also very good. Haven't played much of DMC 5 yet.
