Finding the best magazine for your P365 can depend on many factors and can be quite confusing. This is mainly because the P365 platform includes many different frames, and not all all of the magazines are interchangeable. Thankfully, there are a ton of different magazine options available for each. 

For example, suppose you’re looking for a high-capacity magazine for home defense but a smaller-capacity magazine for everyday carry that will give you enough firepower to get the job done. Depending on your frame, you can most likely find both.

Today, we’ll dive into the most common uses and which specific magazines we recommend for each one.  

Every Day Carry

Everyday carry magazines are meant to be compact while giving you as much firepower as possible. Here are a few magazines for each frame that are ideal for concealed carry. 

P365

Best for Concealment

Smaller magazines are typically harder to control, but the finger rest baseplate helps you find the real estate for your pinky to make your shots more comfortable and controllable. It is also available to those who live in a state with magazine restrictions. 

This durable steel magazine only fits the standard P365 frame, so keep that in mind. If you want to get a little bit fancy, it’s even available with a black or FDE base plate.

Larger Capacity

If you don’t live in a state with restrictions and have a bit more freedom, this magazine also has a finger rest but gives you two more chances to hit your target. It’s almost as concealable as the 10-round magazine, too!

This magazine fits both the P365 and P365XL Frames.

Maximum Capacity

The 17-round X-Macro magazine offers maximum capability and magazine capacity. It comes with three different base plates to fit your specific frame and hands. 

This magazine will extend past the bottom of the grip a considerable amount on the P365. Using the largest baseplate in that case is best so you don’t look so silly. 

P365X and P365XL 

Maximum Concealability

The P365XL and P365X are both easy to carry without worrying about concealability. This 12-round magazine ensures you aren’t inhibiting your movements or jabbing yourself in the stomach if you appendix carry, and minimizes printing. 

As mentioned before, this magazine has the finger rest for your pinky.

In the cooler months, the extra capacity in magazines is easier to conceal, thanks to larger and thicker clothes. As stated above, this magazine comes with three different baseplates, but you’ll utilize a different one than you would with a standard P365.   

P365 X Macro

The X-Macro is the best of both worlds. The P365 slide paired with the P365XL grip module makes the ultimate concealed carry gun, especially for those with larger hands. The best part of that extended grip is the 17-round magazine that comes with the pistol from the factory. 

It is the most versatile of all magazines on this list since it has baseplates to fit all the different frames. 

Home Defense

We’ve already mentioned this one a few times, but it shines the most for home defense. Home defense is an uncertain situation. Are there one or two intruders? Where are they? 

A 17-round magazine is enough to take control of the situation with extra firepower but compact enough to keep you quick and keep the pistol balanced. 

This magazine fits all the P365 frame sizes. 

Range Use 

EDC Drills – Your Choice of Magazine 

I wish I could tell you what magazine is best for EDC drills, but the fact of the matter is the best magazine for your EDC drills is the one that you will be using for EDC. Whether it be the 10-round P365 magazine or the 17-round X-Macro magazine, you should use the same for drills that you do for carrying.

If you have the .380 ACP variant and want to maximize your ability to get your hands around the frame and put rounds on target effectively, having a thumb rest is an excellent way to go, especially if your hands fall on the larger side.

If you have smaller hands that don’t require extra space, you can go with the 10-round magazine. It still has the finger rest for a little added comfort, so you don’t have to worry.

Accessories

Magazine Loaders

It can be quite difficult to load the last round, especially with brand-new magazines. A magazine loader helps you gain the leverage you need to do so easily and quickly. 

Just make sure you aren’t overfilling it! 

Universal Magazine Loader

This magazine loader is one of the most commonly found at different ranges and in shooters’ range bags. Since the UpLULA is close to being universal, you won’t have to carry around multiple loaders for your various pistol magazines. 

Once the magazine(s) are broken in, you won’t need to use it as much, but it’s always an excellent tool to keep close by to give your thumbs a rest.

Conclusion

The Sig Sauer P365 platform comes in many shapes and sizes. Whatever you want to get out of it, there is a P365 for you. Once you have one, you can find any of the magazines you need here at The Mag Shack. 

It never hurts to have spare magazines. You never know when you may need them.

Be good and take care.
