In the never-ending debate about which handgun cartridges are the most effective, shooters traditionally argue for their favorites within the subcategories of pistol cartridges or revolver cartridges. For pistol cartridges, generally the arguments stay within three popular cartridges: 9mm, .40 S&W and .45 ACP. For revolver cartridges, generally the arguments include two calibers: .38 Special and .357 Magnum.

Police departments primarily deploy pistols as sidearms, and usually in one of the three aforementioned pistol calibers. In addition to their duty pistols, police officers often carry backup weapons—usually a subcompact pistol or snub-nosed revolver. Often the duty pistol caliber is different from the caliber of the backup gun. Sometimes the differences can be significant enough to affect performance. Imagine shooting a .45 ACP duty pistol and then quickly changing to a .38 Special snub-nosed revolver while under duress.

Yes, in a desperate situation a police officer or legally armed civilian will of course be thankful for any backup gun. Moreover, the analysis of life-or-death situations involving firearms rarely offers clear-cut universal conclusions. In the pistol/revolver caliber debate, however, consider the potential advantages of carrying a revolver chambered in a pistol caliber. While not an entirely new concept, several firearms manufacturers are currently producing pistol caliber revolvers to serve as backup guns or self-defense/concealed carry guns.
