To be more specific, we’re talking about the age-old debate between 9x19mm Parabellum and .45 ACP. Yes, it’s a classic argument that pits small caliber (9mm) versus large (.45 ACP) and extra capacity versus brute stopping power. While there are many varied opinions on this topic, we turned to a trusted panel of industry experts to weigh-in with their opinions on the matter. The Round Table consists of military, law enforcement, trainers, competitors, gunsmiths and industry insiders. We will always select a multifaceted panel in order to present many different points of view. It’s only natural that everyone won’t share the same opinion, but that’s the great thing about The Round Table. When all of these beliefs are taken as a whole, we can learn something new, spur further debate and perhaps be surprised by what we come away with. The Round Table Has Spoken!

The unanimous decision of our panelists prompted us to take a closer look at 9mm and why it is now held in such high regard. Read on to find out more.
