Appendix inside-the-waistband (AIWB) carry is one of the fastest, most accessible ways to carry concealed—if you pick the right gun. A good AIWB gun needs to be slim, reliable, and comfortable enough to wear all day without digging into you. Here are some solid choices that are easy to conceal and quick to draw when it matters.
Glock 43X
The Glock 43X is about as easy to carry AIWB as it gets. It’s slim enough to disappear under a T-shirt, but it still gives you 10+1 rounds of 9mm. The short grip makes printing less of a problem too.
People like the 43X for its lightweight feel and the familiar Glock reliability. It’s one of those guns you can trust to run no matter what without feeling like you’re lugging around a brick.
SIG Sauer P365
The SIG P365 pretty much changed the game for concealed carry. It’s tiny, but it packs a serious punch with up to 12+1 capacity right out of the box. It’s also snag-free, which is a big deal when you’re drawing from the appendix position.
The P365 feels natural when you’re carrying AIWB because of its short height and rounded edges. It tucks into the waistband without feeling like it’s stabbing you every time you sit down.
Springfield Armory Hellcat
The Springfield Hellcat is another micro-compact that feels tailor-made for AIWB. It’s small, but it still holds 11+1 or even 13+1 rounds depending on your magazine choice. That’s hard to beat in such a tiny package.
It also has a slightly more aggressive grip texture, which helps if you’re carrying in hot weather and your hands get sweaty. Plus, it’s easy to find good AIWB holsters that fit it perfectly.
Smith & Wesson M&P Shield Plus
The Shield Plus took everything people loved about the original Shield and made it better for today’s carry needs. It’s still slim and light, but now you get up to 13 rounds of 9mm in a carry-friendly size.
It’s easy to forget you’re even carrying the Shield Plus after a while. It doesn’t dig into your gut when you sit down, and the flat trigger upgrade makes it easier to shoot well under pressure.
Walther PDP F-Series
The Walther PDP F-Series was built with ergonomics in mind, and it shows. Even though it’s a little bigger than some others on this list, it still feels great AIWB thanks to the slim grip and excellent balance.
Walther designed the F-Series to be easy to rack and shoot, which is great for AIWB carry where you might have less leverage during a fast draw. Plus, the trigger is one of the best you’ll find in a carry gun.
Shadow Systems CR920
The Shadow Systems CR920 brings premium features into a pistol that’s perfectly sized for AIWB. It’s basically the same footprint as a Glock 43X but with upgraded internals and a better trigger feel.
If you want something that’s ultra-reliable but a little more refined than your standard polymer gun, the CR920 is worth a serious look. It fits AIWB holsters made for the 43X too, which makes setup a lot easier.
Glock 48
If you can handle a slightly longer slide, the Glock 48 is a fantastic AIWB option. It’s slim, balanced, and gives you a longer sight radius for easier shooting without feeling bulky.
The 48 is popular for people who want a little more control without giving up concealability. Paired with a good AIWB holster, it rides low and flat against your body for all-day comfort.
Ruger Max-9
The Ruger Max-9 is a budget-friendly choice that still checks all the right boxes for AIWB carry. It’s small, lightweight, and gives you 10+1 or 12+1 rounds depending on the magazine.
It also comes optic-ready if you’re into red dots, which can be a huge bonus for fast shooting from the appendix position. For the price, it’s tough to find a better micro-compact that feels this comfortable to carry.
Kimber R7 Mako
The Kimber R7 Mako is another micro-compact built for serious everyday carry. It’s fully enclosed, which means you’re less likely to get dirt and grime into the action—a nice plus for AIWB where sweat is a factor.
It feels a little chunkier than a P365 but still carries comfortably. The trigger is crisp, and the sights are easy to pick up fast if you ever have to draw under stress.
FN 503
The FN 503 is a sleeper pick for AIWB carry. It doesn’t get talked about as much, but it’s slim, snag-free, and incredibly reliable. It holds 6+1 or 8+1 rounds depending on the mag you run.
The single-stack design makes it one of the flattest guns you can carry, which matters a lot when you’re wearing it all day up front. It’s simple, tough, and easy to shoot well under pressure.
