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.
