In this post, I will make the case for the small, discreetly carried .22 Long Rifle (22) caliber pistol.
22 HISTORY
The 22 LR is an old cartridge, introduced in 1887, For a short history of the cartridge, see this page from Smith & Wesson. Many manufacturers around the world produce ammo in this caliber.
WHY USE THE 22 AS A DEFENSIVE PISTOL
There are several reasons for using the 22 pistol as a defensive weapon. 22 ammo is relatively inexpensive. One can get it in bulk quantities for as little as 6¢ per round plus shipping in quantities of 500 rounds (as of October, 2022). This ammo has very little recoil, since it is relatively low-powered. 22 pistols are not nearly as noisy as centerfire pistols. They are easier for the novice to learn to shoot.
There are 22 handguns that range in size from pocket pistols such as the Ruger LCP II 22 and Beretta M21; to mid size pistols such as the Smith & Wesson M&P 22 compact, the Glock 44, and Ruger SR22; to various full size handguns. This discussion will focus on the smaller handguns, since our primary objective is to look at discreet carry.
