While cartridge choice, projectile type, velocity and more have changed much over the years, the basic dynamics have remained the same.

Currently, we are seeing an increase of 10mm handguns produced versus a decrease of .40 handguns. Is it true that many shooters are opting for the 10mm round over the .40?<\/p>\n<p>The fact is, both the .40 and the 10mm share the same head-case diameter of 0.424\u201d headspace off the case of the mouth. Therefore, they are similar in many ways yet vastly different in others. Before I get into that, let us first take a look back in history.<\/p>\n<h2>Catalyst for Debate: Miami Shootout<\/h2>\n<p>Back in 1986, two violent criminals engaged in an intense shootout with field agents in what has become known as the \u201cMiami Shootout.\u201d The FBI agents partially surrounded the criminals, and bullets began flying. The agents quickly learned that their firepower was outmatched by that of the criminals, who had long guns as well as handguns and had trained intensively for a fight like that.<\/p>\n<figure class=\"wp-block-image size-full\"><picture decoding=\"async\" loading=\"lazy\" class=\"wp-image-38872\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-800x450.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-400x225.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-768x432.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-600x338.jpg.webp 600w\" sizes=\"(max-width: 1400px) 100vw, 1400px\"\/><img decoding=\"async\" loading=\"lazy\" width=\"1400\" height=\"788\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil.jpg\" alt=\"testing 40 vs 10mm for recoil\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-800x450.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-400x225.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-768x432.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/testing-40-vs-10mm-for-recoil-600x338.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">The 1911 platform is one of the most popular handguns for the 10mm cartridge. Many people use it for hunting, defense and\u00a0competition.<\/figcaption><\/figure>\n<p>At that time, the agents were using .38 Special revolvers as their primary source of defense, as well as a 9mm pistol. The FBI agents were ultimately successful, but not without casualties. The two criminals were killed, but so were two agents, along with five injured. This event forced the FBI to rethink their defensive ammunition choice.<\/p>\n<h2>More Stopping Power<\/h2>\n<p>The Miami Shootout forced the FBI to investigate their choice of duty firearms. They eventually decided to adopt 10mm semi-auto pistols to prevent the Miami Shootout scenario from happening again. They believed that with more stopping power, increased capacity and the ease of reloading, the 10mm round would level the playing field with hardened criminals.<\/p>\n<figure class=\"wp-block-image size-full\"><picture decoding=\"async\" loading=\"lazy\" class=\"wp-image-38878\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2.jpg.webp 1398w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-800x267.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-400x133.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-768x256.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-600x200.jpg.webp 600w\" sizes=\"(max-width: 1398px) 100vw, 1398px\"\/><img decoding=\"async\" loading=\"lazy\" width=\"1398\" height=\"466\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2.jpg\" alt=\"10mm vs 40 stopping power gel penetration\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2.jpg 1398w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-800x267.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-400x133.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-768x256.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/10mm-vs-40-stopping-power-gel-penetration-v2-600x200.jpg 600w\" sizes=\"auto, (max-width: 1398px) 100vw, 1398px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">Both the .40 and 10mm have premium defensive loads that deliver excellent accuracy and optimum\u00a0penetration.<\/figcaption><\/figure>\n<p>The adoption of the 10mm semi-auto pistols was supposedly cut short due to complaints of excessive recoil. The FBI requested a smaller round with similar bullet dimensions. The result was the .40 caliber round in 1990. They decided to shorten the round case and produce a 180-grain bullet that traveled around 1,000 feet per second.<\/p>\n<h2>.40 vs. 10mm: Similar, but Different<\/h2>\n<p>Having said all of that, let\u2019s discuss the differences.

On average, the 10mm will travel at 1,250 feet per second and deliver 624 foot pounds of muzzle energy. The .40 has a decreased velocity of 1,000 feet per second with 400 foot pounds of energy. When shooting, higher velocity and foot pounds of energy equates to increased recoil and reduced muzzle control. Basically, the .40 round is a scaled down 10mm.<\/p>\n<h2>What Are Our Options?<\/h2>\n<p>While the .40\u2019s popularity might be waning, the 10mm is coming on strong.

But, it\u2019s hard to argue with the increased capacity of the 9mm.<\/p>\n<figure class=\"wp-block-image size-full\"><picture decoding=\"async\" loading=\"lazy\" class=\"wp-image-38877\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-800x470.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-400x235.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-768x451.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-600x352.jpg.webp 600w\" sizes=\"(max-width: 1400px) 100vw, 1400px\"\/><img decoding=\"async\" loading=\"lazy\" width=\"1400\" height=\"822\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo.jpg\" alt=\"xd40 with 40 s&amp;w ammo\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-800x470.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-400x235.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-768x451.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/01\/xd40-with-40-sw-ammo-600x352.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">Which is best: 10mm or .40?

No matter where you stand on the <a href=\"http:\/\/www.thearmorylife.com\/is-everything-you-know-about-40-wrong\/\">9mm vs. .40 vs. .45 debate<\/a>, Springfield offers capable guns in all three chamberings. The firearms I featured here have performed flawlessly.<\/p>\n<p>As for me, let\u2019s just say, I am a fan of each. However, the 1911 Ronin and the <span class=\"nowrap\">XD-M<\/span> Elite 3.8 Compact OSP chambered in the powerful 10mm have won over my heart.
