After You Buy - SIG Sauer P365-XMACRO COMP Maintenance

Last time we talked about the SIG Sauer P365-XMACRO COMP it was in the context of whether or not the pistol was a good fit for you and your shooting needs. I’ve owned one of these handguns since their initial release in August of 2022 and since then I’ve shot mine a bunch and in the course of that shooting I’ve had to maintain and service the pistol properly. While the P365-XMACRO COMP is largely similar to every other Sig Sauer P365 out there, it does have a few differences that make it worth looking into when you’re trying to clean it. So today we’ll go over how to clean the SIG Sauer P365-XMACRO COMP!

How To Disassemble P365 XMacro

As with any cleaning guide, this one starts with the mindset that we should treat all firearms as if they are loaded. You’ll first need to remove the magazine from the firearm and set it away from your workspace, you’ll then need to clear the gun and both visually and physically inspect the chamber to make sure it is clear. After that bit of safety check is in place, you can go ahead and leave the slide locked to the rear for now. You’ll also want to take this opportunity to unload any magazines you have if you haven’t already as we’ll be cleaning those as well.

To field strip the SIG P365-XMACRO COMP you’ll have to make sure the slide is locked to the rear, and then you’ll need to rotate the takedown pin clockwise (down and away from the slide)  until it locks itself into place.

After that, you can remove the slide by moving it forward on the pistol frame. Next, you can flip the slide upside down and push the recoil spring guide slightly forward to disengage it from the barrel lug. Once this is done you can remove both the recoil spring and barrel by sliding them rewards and out of the slide.

Your magazines can also be easily disassembled by using a small punch or other pushing tool to press on the insert stud until it is disengaged from the magazine floorplate. After this you can slide the floorplate forward and off of the magazine tube taking special care to safely relieve the spring tension before removing the insert, spring, and follower from the magazine tube. With these two steps done, you can now clean and maintain all the of the most critical components of the SIG Sauer P365-XMACRO COMP. SIG Sauer officially discourages any further disassembly of the firearm in their manual.

Magazine Cleaning

The magazines require very little maintenance and aside from routine clearing of exterior debris and dust, I’d only recommend fully disassembling and cleaning your magazines occasionally rather than every time you clean the firearm. You can wipe the exterior of the magazine tube the the follower with a soft nylon brush and your favorite CLP. After a good scrub down of the magazine tube and follower, you can dry everything up with some paper towels or a clean cloth to wipe away all the gunk. After this, you can reassemble the magazine and apply a very light coat of CLP to the exterior of the magazine body.

Barrel, Recoil Spring, and Slide Cleaning

Before cleaning you’ll want to wipe down as much of the pistol's components as possible. This will remove all of the old CLP from your last cleaning and remove a majority of the large debris so that cleaning will go more smoothly.

The slide can be cleaned with a soft or medium nylon brush and a healthy amount of CLP. After everything has been scrubbed down you can wipe away all of the CLP and then apply a light coat of CLP to the frame rail slots of the slide and use a clean cloth or cleaning patch to apply another light coat of CLP To the exterior of the slide. Lubrication not only helps with smooth mechanical operation of your P365, but also conserves the metal and prevents corosion.

You can soak your barrel in some CLP to help with cleaning but other than that you can use any standard non-steel wire brush and a set of cleaning patches to clean the barrel of the pistol. The feed ramp should be cleaned with a nylon brush and the entirety of the barrel should be wiped dry with cleaning patches - this is one area of the pistol that you do not want your CLP sitting as it could affect the reliability of any ammunition chambered and loaded in the handgun during normal carry.

SIG Sauer recommends replacing the recoil spring guide assembly every 2,500 rounds. You should not disassemble the recoil spring as it’s serviced as a single unit and SIG Sauer will just send you the entire recoil spring and guide rod assembly when you order a new one. Cleaning is fairly straightforward, you can use a soft brush and CLP to scrub down, wipe clean, and re-lubricate the entire assembly before reinstalling all the components into the complete slide assembly.

Exterior Cleaning

The Frame and or Grip Module on the P365 is made from polymer so you should take care not to use any harsh chemicals that might damage the grip module. At this level of cleaning your P365’s FCU (Fire Control Unit) shouldn’t be removed and as a result, we’ll treat both the FCU and Grip Module as one piece “the frame.” If you’re concerned about the amount of dirt and dead skin built up in the grip texture of your firearm, you can use a large dry stiff bristled nylon brush to remove the gunk.

Once the exterior is cleaned, you can wipe down the frame rails paying special attention to the areas beneath the frame rails where carbon tends to build up over time. You can use cotton swabs or folded pieces of cleaning patches to get into these hard-to-reach areas. After everything has been cleaned properly, you can reapply a small amount of CLP to the frame rails, magazine catch, slide catch, takedown lever, and other interior parts of the FCU and frame.

Special Areas of Attention

The ports on the integrated slide compensator will build up carbon residue a lot faster than the rest of your P365 X Macro. Frequent cleaning of the slide might be necessary and these deposits can be quite difficult to break up during a quick cleaning. In these cases, you may want to soak the compensator in some CLP for several minutes to help soften the carbon deposits. The same can be applied to the crown of the barrel if you happen to notice a build-up of carbon deposits on the muzzle.

Other areas that are critical for cleaning include the extractor on the slide assembly. The extractor claw tends to get gunk inside of it during cleaning so you must pay special attention to it and make sure to scrub, scrape, and dry this piece to make sure your pistol runs reliably.

With everything clean, all that you need to do is reassemble the pistol in the reverse order you disassembled it in! After that, take another moment to wipe down the metal parts with a very light coat of CLP and a dry cloth, and then admire your work and your clean Sig P365 XMacro!

And my last advice. Once this is done, do not forget to also clean your Sig P365 Xmacro holster as a dirty holster might ruin your cleaning job in a matter of seconds.
