Survival Debate: 9mm or .45

We’re starting a new series on to discuss the most common and popular debates among survivalists. I figured what better way to start than with the grand daddy of them all: 9MM or .45.  Everybody has an opinion on this one, and if you don’t you probably need one, for conversational purposes if nothing else.

Beretta 92FS

Beretta 92FS – 9mm



  • 40-50% Cheaper
  • Lower Recoil
  • Higher Capacity Magazine
  • Currently U.S. Military sidearm (Beretta)
  • Higher Velocity – 1100-1300 FPS


  • Less Knockdown Power
Colt 1911

Colt 1911 – .45



  • More Knockdown Power
  • Ex-Military Sidearm (Colt 1911)


  • Twice as Expensive
  • Smaller Capacity Magazine
  • More Recoil
9mm 40 45 bullets

9mm, .40 S&W, .45 ACP

Middle Ground

Every great debate has a middle ground. For this one it would be the .40 S&W Caliber. It has more power than the 9MM, but can still hold more rounds per magazine than the .45. The price is also in the middle. The .40 round is widely adopted by Police and Law Enforcement all over the world.

However, this compromise doesn’t seem to sway avid fans very much. Most polls, while certainly not scientific, usually show a huge divide between 9MM and .45 with the .40 being a distant third.

Where do you stand?

Personally I am a 9MM fan, but I might be heavily swayed by the fact that it is far cheaper and I don’t have a lot of money. If cost wasn’t an object I might lean towards .45- Leave a comment and tell us which you prefer and why.
