The P365 was designed around a new double-stack 10-round magazine, offering unprecedented capacity in a very concealable package. It single-handedly killed the previously robust single-stack 9mm market. My Walther PPS was my main EDC gun until I got a P365XL. Now the PPS mostly gathers dust. Sometimes it gets to play backup gun.<\/p>\n<figure id=\"attachment_404332\" aria-describedby=\"caption-attachment-404332\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"wp-image-404332 size-full lazyload\" data-src=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag.jpg\" alt=\"Sig Sauer P365XL with magazine and ammo, sig p365 mags\" width=\"800\" height=\"600\" data-srcset=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag.jpg 800w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-300x225.jpg 300w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-768x576.jpg 768w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-150x113.jpg 150w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/600;\" \/><figcaption id=\"caption-attachment-404332\" class=\"wp-caption-text\">Sig designed the P365 series around their new double-stack magazine.

Even better, those mags will also run in the original P365. I recently ordered some of those mags for my P365XL and was surprised when they automatically came with a grip extension for the P365. You can tell how much attention I paid when I hit \u201cadd to cart.\u201d But no big deal because these mags work with either gun. I just don\u2019t need the grip extension, nor does it work with the X or XL variants. But we\u2019ll cover the extension while we talk about the mags because it\u2019s a nice inclusion.<\/p>\n<p>My P365XL is my primary carry gun, so it gets a lot of range work. So do the magazines. I only have six mags, so I\u2019m making a decided effort to expand my pool. Probably like most of you, mag changes figure into many of my drills, so those mags get knocked around. I\u2019m constantly dropping them on the gravel-lined ground while I train. I\u2019ve had the Sig for just over a year now, so that\u2019s a lot of mag changes. They get dinged and dirty, but they\u2019ve always come right back and run like I expect them to.<\/p>\n<figure id=\"attachment_404335\" aria-describedby=\"caption-attachment-404335\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-404335 lazyload\" data-src=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl.jpg\" alt=\"Sig Sauer P365XL\" width=\"800\" height=\"600\" data-srcset=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl.jpg 800w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-300x225.jpg 300w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-768x576.jpg 768w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-150x113.jpg 150w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/600;\" \/><figcaption id=\"caption-attachment-404335\" class=\"wp-caption-text\">12+1 in a subcompact. I dig it. (Author&#8217;s Photo)<\/figcaption><\/figure>\n<h2><strong>Mag Specifications<\/strong><\/h2>\n<p>The proprietary Sig Sauer mags aren\u2019t cheap, but they are well made. Here are the basic specifications:<\/p>\n<ul>\n<li>Capacity: 12 rounds 9mm Luger<\/li>\n<li>Double stack<\/li>\n<li>Nitride-coated steel body<\/li>\n<li>Polymer floor plate<\/li>\n<li>High-tensile steel spring<\/li>\n<li>Heat-treated, anti-tilt polymer follower<\/li>\n<li>Factory drilled and numbered witness holes<\/li>\n<li>Extended grip floor plate for P365<\/li>\n<li>Flush floor plate for P365X and P365XL<\/li>\n<\/ul>\n<h2><strong>A Great Design<\/strong><\/h2>\n<p>As noted, Sig Sauer first designed the <a href=\"https:\/\/gunmagwarehouse.com\/sig-sauer-p365-9mm-10-round-magazine.html\">10-round P365 magazine<\/a>. Then they designed the pistol around it. Kind of makes me wonder why someone didn\u2019t think of that sooner. Maybe they did, for all I know, but Sig knocked it out of the park. Then they added two rounds for the X and XL guns. I love my Walther PPS M2, but its maximum capacity is 8+1. My P365XL is 12+1 AND the Sig is smaller than the PPS. No knock on the PPS. It\u2019s just a different approach to a different philosophy.<\/p>\n<p>I like that the 12-round mag works with the original P365, but the way it hangs out of the mag well looks goofy and could possibly snag on clothing. Sig addresses that with this grip extender. Note that it\u2019s a <em>grip<\/em> extender, not a <em>magazine<\/em> extender. It\u2019s meant to improve your grip with the 12-round mag. The two extra rounds are already included. The extender is textured exactly like the pistol\u2019s grip, so it\u2019s almost seamless. It\u2019s a very nice feature.<\/p>\n<p>The only issue I have with the extender is that installation isn\u2019t exactly intuitive, and instructions aren\u2019t included. I had to find a YouTube video. But it was easy enough once I got that straight:<\/p>\n<ul>\n<li>Remove the extender\u2019s floor plate.<\/li>\n<li>Remove the magazine\u2019s flush floor plate.<\/li>\n<li>Hold the mag spring down while pressing the extender\u2019s sleeve onto the mag\u2019s bottom until it\u2019s snug.<\/li>\n<li>Insert the extender\u2019s floor plate, making sure the follower\u2019s lug fits in the plate\u2019s center hole.<\/li>\n<\/ul>\n<p>The process may sound simple, and it really is. But it\u2019s not readily apparent just from looking at the extender.<\/p>\n<figure id=\"attachment_404333\" aria-describedby=\"caption-attachment-404333\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-404333 lazyload\" data-src=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-profiles.jpg\" alt=\"Sig Sauer P365 12-round magazine with grip extender\" width=\"800\" height=\"300\" data-srcset=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-profiles.jpg 800w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-profiles-300x113.jpg 300w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-profiles-768x288.jpg 768w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365-12-rd-mag-profiles-150x56.jpg 150w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/300;\" \/><figcaption id=\"caption-attachment-404333\" class=\"wp-caption-text\">The grip extender has the same texture as the P365&#8217;s grip. (Author&#8217;s Photo)<\/figcaption><\/figure>\n<h2><strong>Magazine Performance<\/strong><\/h2>\n<p>These are quality mags, as you\u2019d expect. They\u2019re solid and they work. I\u2019ve never had a single feeding issue with my P365XL. That will obviously happen at some point, but I don\u2019t think it will happen because of faulty mags. Unless, perhaps, I wear them out, which does happen, even to the best mags. Magazines are commodities to be used. Buy some more.<\/p>\n<p>The only issue I\u2019ve had is magazine ejection, and that isn\u2019t the mags\u2019 fault. The P365\u2019s mag release button is smaller and less positive than I like. I want a button that I can hit with ease, and I want the mags to launch out of the mag well. Some guns do that better than others. The Sig doesn\u2019t do it as well as I\u2019d prefer. But, again, that\u2019s the gun, not the mags.<\/p>\n<p>The mag springs are very strong, to the point of needing a <a href=\"https:\/\/gunmagwarehouse.com\/accessories\/loaders\/handgun-magazine-loaders\">mag loader<\/a> to fill them up all the way. I always download my pistol mags by one round, but I usually fill it up and then rack the slide to chamber the first round. I like that robust spring. The follower also seems very solid. Polymer followers are polymer followers, but this one seems a bit more solid than others. Maybe because the spring keeps it tight against the feed lips. I can\u2019t say for certain. But it has never failed to lock the slide back when I\u2019m empty. Nor has it ever prematurely dropped the slide when I insert a fresh mag. I\u2019ve had other brands do that on occasion.<\/p>\n<figure id=\"attachment_404334\" aria-describedby=\"caption-attachment-404334\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-404334 lazyload\" data-src=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-range.jpg\" alt=\"Sig Sauer P365XL\" width=\"800\" height=\"600\" data-srcset=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-range.jpg 800w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-range-300x225.jpg 300w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-range-768x576.jpg 768w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2023\/07\/sig-p365xl-range-150x113.jpg 150w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/600;\" \/><figcaption id=\"caption-attachment-404334\" class=\"wp-caption-text\">The Sig Sauer P365XL just runs.
