Both date back to the late nineteenth century.<\/p>\n<p>But this is where the similarities end.<\/p>\n<p>One is rimfire, the other is centerfire. One is used in rifles and pistols of all sorts, while the other is limited, almost exclusively, to semiautomatic pistols.<\/p>\n<p>They are the .22 Long Rifle and the .32 ACP cartridges. While they have their limits (and plenty of derision), either can be used for personal protection.<\/p>\n<p>Thinking of getting one of these small, manageable, easily concealed rounds for your daily carry or as a backup option? Either one is better than no gun at all, so if you are selecting a personal-protection round, you need to research thoroughly before investing in a conceal-carry pistol. After all, a personal defense weapon is arguably the most important firearm a person will ever purchase.<\/p>\n<p>So let\u2019s dive deeper to see if one or both of these rounds are up to the task\u2026<\/p>\n<p><strong>Note: Comparing These Cartridges as Handgun Rounds Only<\/strong><br \/>\nYou can use both of these cartridges for more than personal defense. However, the .32 ACP is almost exclusively a conceal-carry personal defense round, while the .22 LR is more for plinking, small-game hunting, and varmint control. However, the .22, despite plenty of naysayers, can be used for personal protection. This is the main overlapping purpose of these rounds, so we are going to compare the two through the lens of personal defense and conceal-carry.<\/p>\n<h2>.22 LR vs .32 ACP Specs<\/h2>\n\n<table id=\"tablepress-369\" class=\"tablepress tablepress-id-369\">\n<thead>\n<tr class=\"row-1\">\n\t<td class=\"column-1\"><\/td><th class=\"column-2\">.22 Long Rifle<\/th><th class=\"column-3\">.32 ACP<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-2\">\n\t<td class=\"column-1\">Released<\/td><td class=\"column-2\">1887<\/td><td class=\"column-3\">1899<\/td>\n<\/tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\">Case Type<\/td><td class=\"column-2\">Rimfire<\/td><td class=\"column-3\">Centerfire<\/td>\n<\/tr>\n<tr class=\"row-4\">\n\t<td class=\"column-1\">Bullet Diameter<\/td><td class=\"column-2\">.223 inches<\/td><td class=\"column-3\">.3125 inches<\/td>\n<\/tr>\n<tr class=\"row-5\">\n\t<td class=\"column-1\">Neck Diameter<\/td><td class=\"column-2\">.226 inches<\/td><td class=\"column-3\">.3365 inches<\/td>\n<\/tr>\n<tr class=\"row-6\">\n\t<td class=\"column-1\">Base Diameter<\/td><td class=\"column-2\">.226 inches<\/td><td class=\"column-3\">.337 inches<\/td>\n<\/tr>\n<tr class=\"row-7\">\n\t<td class=\"column-1\">Case Length<\/td><td class=\"column-2\">.613 inches<\/td><td class=\"column-3\">.680 inches<\/td>\n<\/tr>\n<tr class=\"row-8\">\n\t<td class=\"column-1\">Overall Length<\/td><td class=\"column-2\">1 inch<\/td><td class=\"column-3\">.984 inches<\/td>\n<\/tr>\n<tr class=\"row-9\">\n\t<td class=\"column-1\">Bullet Weights<\/td><td class=\"column-2\">Roughly 20 - 60 grains<\/td><td class=\"column-3\">55 - 75 grains<\/td>\n<\/tr>\n<tr class=\"row-10\">\n\t<td class=\"column-1\">Typical Firearm<\/td><td class=\"column-2\">Rifles and handguns of all types<\/td><td class=\"column-3\">Semiautomatic pistols<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<!-- #tablepress-369 from cache -->\n<h2>22LR versus 32 ACP: Size and Shape Differences<\/h2>\n<figure id=\"attachment_83832\" aria-describedby=\"caption-attachment-83832\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-83832 size-full\" title=\"22 LR ammo side by side with 32 ACP ammo\" src=\"https:\/\/www.ammunitiontogo.com\/lodge\/wp-content\/uploads\/DSC7983-Web.jpg\" alt=\"22 LR ammo side by side with 32 ACP ammo\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.ammunitiontogo.com\/lodge\/wp-content\/uploads\/DSC7983-Web.jpg 1024w, https:\/\/www.ammunitiontogo.com\/lodge\/wp-content\/uploads\/DSC7983-Web-300x200.jpg 300w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption id=\"caption-attachment-83832\" class=\"wp-caption-text\">22 LR ammo (left) side by side with 32 ACP ammo (right)<\/figcaption><\/figure>\n<p>If you hold both of these rounds in your hand, you\u2019ll immediately notice that .32 ACP is wider and has more mass. This is fairly predictable given the numerical names of the two. What may be surprising, however, is that the .22 LR is just a bit longer than the .32 ACP, making the .32 appear squat by comparison.<\/p>\n<h3>Grain Weights<\/h3>\n<p>The larger diameter of the .32 ACP plays a role in the available bullet weights. With a wider diameter, the bullets in the .32 ACP can be heavier, although not by a significant margin. There is plenty of overlap, but the .32 ACP will pack larger, heavier bullets.<\/p>\n<h3>Market Conditions<\/h3>\n<p>The .32 ACP is not a rare cartridge by any means, but the .22 LR is one of the most readily available cartridges on the market. Defense-specific rounds may be harder to come by (although certainly not impossible), but you should have little trouble finding .22 rounds for a variety of purposes.<\/p>\n<h2>Ballistics Comparison: .22 LR vs. .32 ACP<\/h2>\n<h3>Velocity<\/h3>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-83833 size-full\" title=\"Shooting 22 LR\" src=\"https:\/\/www.ammunitiontogo.com\/lodge\/wp-content\/uploads\/DSC5926-Web.jpg\" alt=\"Shooting 22 LR at the range in front of a chronograph\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.ammunitiontogo.com\/lodge\/wp-content\/uploads\/DSC5926-Web.jpg 1024w, https:\/\/www.ammunitiontogo.com\/lodge\/wp-content\/uploads\/DSC5926-Web-300x200.jpg 300w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n\n<table id=\"tablepress-371\" class=\"tablepress tablepress-id-371\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\">Ammo<\/th><th class=\"column-2\">Muzzle Velocity (fps)<\/th><th class=\"column-3\">25-Yard Velocity<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-2\">\n\t<td class=\"column-1\">22LR - Winchester 37-gr Silvertip<\/td><td class=\"column-2\">1,060<\/td><td class=\"column-3\">1,011<\/td>\n<\/tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\">32 ACP - Winchester 60-gr Silvertip<\/td><td class=\"column-2\">970<\/td><td class=\"column-3\">930<\/td>\n<\/tr>\n<tr class=\"row-4\">\n\t<td class=\"column-1\"><\/td><td class=\"column-2\"><\/td><td class=\"column-3\"><\/td>\n<\/tr>\n<tr class=\"row-5\">\n\t<td class=\"column-1\">22LR - Federal 29-gr Punch<\/td><td class=\"column-2\">1,080<\/td><td class=\"column-3\">N\/A<\/td>\n<\/tr>\n<tr class=\"row-6\">\n\t<td class=\"column-1\">32 ACP - Federal 65-gr Hydra-Shok<\/td><td class=\"column-2\">925<\/td><td class=\"column-3\">892<\/td>\n<\/tr>\n<tr class=\"row-7\">\n\t<td class=\"column-1\"><\/td><td class=\"column-2\"><\/td><td class=\"column-3\"><\/td>\n<\/tr>\n<tr class=\"row-8\">\n\t<td class=\"column-1\">22LR - Blazer 40-gr LRN<\/td><td class=\"column-2\">1,235<\/td><td class=\"column-3\">N\/A<\/td>\n<\/tr>\n<tr class=\"row-9\">\n\t<td class=\"column-1\">32 ACP - Blazer 71-gr FMJ<\/td><td class=\"column-2\">900<\/td><td class=\"column-3\">N\/A<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<!-- #tablepress-371 from cache -->\n<p>For speed, <a href=\"https:\/\/www.ammunitiontogo.com\/22-rimfirelr-mag-22-long-rifle\">22 Long Rifle ammo<\/a> is the faster round, even from pistol-length barrels.

Energy can make a large difference in how the bullet delivers damage to the target. That can impact whether or not you stop a threat immediately.<\/p>\n<p>Neither of these rounds is considered a high-powered option, but the .32 ACP is, in general, considered the more powerful round. But as we can see from these results, the .22 LR actually holds its own against the .32. Two of the three head-to-head comparisons showed higher energy stats for the .32 ACP but the most powerful round in this sample was the 40-grain .22 LR from CCI. This may not be surprising, as this round was also the fastest; speed generally creates more energy.<\/p>\n<h3>Recoil?<\/h3>\n<p>The ideal ammunition will be powerful enough to stop a threat yet deliver a soft recoil that makes shooting comfortable and easy. With either of these rounds, recoil will not be an issue. Both deliver two of the softest kicks in the shooting industry.<\/p>\n<p>The .22 LR is known for light recoil, which is why it\u2019s the round of choice for learning to shoot with rifles and handguns. Many introductory handgun courses feature hands-on shooting with the .22. The .32 is not far behind; it too delivers a comfortable, manageable kick, although it\u2019s a bit harder than the .22.<\/p>\n<p>Recoil may be important, but most shooters will not select one or the other based solely on this factor.<\/p>\n<h3>Which One is \u201cBest\u201d for Personal Protection?<\/h3>\n<p>Honestly, the statistics for the .22 LR and the .32 ACP are closer than you may have expected, which makes choosing one or the other a bit more difficult. Overall, however, it\u2019s safe to say that the .32 ACP is generally the more powerful and effective round for conceal carry and personal protection.<\/p>\n<p>While many feel <a href=\"https:\/\/www.ammunitiontogo.com\/pistol-ammo-32-auto\">.32 ACP ammo<\/a> is too weak to rely on, if you want a decent round that pairs with easy-to-conceal firearms, the .32 ACP is a fine choice. You won\u2019t be shooting through car doors (nor should you), but you\u2019ll have a weapon you can use for close-range critical situations. (We go in-depth covering <a href=\"https:\/\/www.ammunitiontogo.com\/lodge\/32-acp-for-self-defense\/\">32 ACP for self-defense here<\/a>.)<\/p>\n<p>But .22 LR still has its uses. If you want a light pistol that can be concealed easily, something that provides a better-than-nothing means of defense, but also creates an available, affordable option for high-volume range shooting, the .22 suits you perfectly.<\/p>\n<h3>You Don\u2019t Have to Overpay to Defend Yourself<\/h3>\n<p>Visit ammotogo.com for affordable ammunition at a fair price.
