9mm vs. 45 ACP

9mm vs 45 ACP–A Different Kind of Comparison

The 9mm vs 45 ACP argument has been going on for more than a century. Many believed the two World Wars answered this question after Americans used their .45s to beat the Germans and their 9mms— twice. But in 1967, the Illinois State Police adopted the Smith & Wesson Model 39 pistol in 9mm, and in 1985 the U.S. Military transitioned from their war-winner to the Beretta M9.
