Our round table of military, law enforcement and other industry experts answers the age-old debate between .45 ACP and 9mm ammo.

Of the many debatable topics of conversation in the firearms world, one that pops up a lot more often than others, relates to caliber. 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.

FK – I have to agree with the ‘experts.’ It’s all about what feels good to you and what you can hit with. I carried a .40 for a while and never liked the recovery time due to recoil. When the average person knows they’re hit and sees blood they’re out of the fight. A .45 might be good to keep handy in the car if carjackings are an issue where you live or commute but most 9mms are easier to carry, handle and have more rounds for better crowd control.
