It’s no secret that SIG Sauer’s P365 9mm is among the most popular and in-demand pistols on the market. Whether you already have one of these mighty micro-compact handguns or not, wouldn’t you like to hear how you can take your P365 to the next level?

Accessories are not only a means of personalizing your gun, but also a way to improve its capabilities. SIG Sauer designed the P365 9mm to pair seamlessly with dozens of different accessory types. Between barrels, sights, holsters, magazines, and more, there is an abundance of unique accessory combinations possible to situate your gun.

The SIG P365 9mm is ready to be carried right out of the box. However, the standard configuration may not be ideal for certain usage situations. Accessories can help solve this problem and propel you closer to ensuring your gun is equipped for any scenario.

For example, there may come a time when you need to shoot in the dark. In such a case, adding night sights to your gun would help you get a faster, safer, and smoother lock on your target.

Similarly, if concealed carry is your modus operandi, there are some “trappings” you can affix to your 9mm to make it a better everyday carry (EDC) gun.

The Philosophy of Upgrading

When upgrading your firearms, a strategy for determining which accessories to purchase is to look at the gun's inherent weaknesses or simply missing preferences, and determine how to address them.

Like most small handguns, the P365 has limitations in a few areas:

• Short sight radius
• Muzzle rise
• A proprietary rail system that limits compatibility compared to other models

After identifying these key aspects of the pistol, you can focus on supplementing the configuration with accessories that will improve your overall user experience.

Here are five upgrades you might consider for your SIG P365 to customize and create your perfect concealed-carry companion:

Upgrade #1 - A Lighter SIG P365 Barrel

True Precision’s P365 BBL 9mm BLK NIT barrel helps cut weight and can cycle any type of ammo through its advanced proprietary broach-cut design. This barrel is engineered for increased accuracy potential and an extended barrel life.

The fit and finish are spot-on, which prevents problems with running defense or range ammo through it. The coating color is a medium matte gray, intensifying the aesthetics of the P365 even more. In addition, the exterior design includes a multitude of grooves that wrap around the circumference of the barrel.

True Precision manufactures a wide array of high-quality parts and components for firearms, prioritizing personal defense. And all of their products are designed and produced here in the USA.

Additional Barrel Options to Check-Out:

• True Precision SIG Sauer P365 Threaded Barrel
• True Precision P365 BBL 9mm Stainless TB

Upgrade #2 - Precision-Stripped Slide

Rival Arms’ SIG P365 A1 RMS BLK slide creates an efficient cooling airflow and cuts cleaner than the out-of-the-box stock version.

With recessed slide cuts (a.k.a. a ported slide) and aggressive front and rear serrations, this slide improves overall performance by giving you more to grip and cuts the overall weight of the gun. It also rocks a 416R matte-black finish and comes with a cover plate for an optics mounting option.

For a much brighter design aesthetic, you could consider Grey Ghost’s Precision (GGP) Stripped Slide for SIG P365. This slide features a handy cut-out for a red dot sight.

Compatible with Shield Rms-c and Romeo Zero with supplied screws, GGP’s model ships with everything you need to affix it to your pistol. If tan-colored accessories are more your style, GGP’s V1 FDE for SIG P365 offers a cerakote finish that would fit the bill.

Upgrade #3 - A Clean-Firing SIG P365 Trigger

One of a firearm's most important anatomical pieces is the trigger. High-quality triggers result in a gun that is consistent and can be relied upon.

Because many factory triggers possess minor imperfections and rough surfaces, it can be challenging to achieve a smooth, clean-action firing experience. It is sometimes therefore best to have a professional armorer polish your factory trigger assembly—or to replace the factory trigger entirely.

M CARBO sells a flat trigger upgrade for the SIG Sauer P365 with metal injection molded parts to correct factory trigger problems. With an improved trigger reset angle and a tumbled smooth, black nitride lifetime finish, the flat design allows you to place your finger lower on the trigger, making the pull a full half pound lighter.

The Short Stroke Flat Trigger Upgrade by M CARBO fits all models of the SIG P365, and includes an over-travel set screw adjustment to achieve max reduction.

Upgrade #4 - Don’t Sleep On Night Sights

There may come a time when you need to shoot but don’t have a good light source. Similarly, an excess of white light can also make it difficult to see your target. Although night sights do not eliminate the need for one or more artificial light sources, they can help you aim more accurately in limited lighting.

The Truglo Brite-Site TFX for SIG P365 is a sight set for both day and night. The front of the sight is green with a white focus lock ring. This design allows it to glow in the dark without batteries or required light exposure.

Another solid sight option is the HS507K X2 by Holosun. This open reflex optical sight model was explicitly designed for concealed-carry applications.

Why You Should Upgrade Your SIG P365

The SIG Sauer P365 is truly one of the best-concealed carry weapons you can purchase. Because of its small form factor, lightweight build, and significant loading capacity, it checks all boxes for everyday carry.

Even without any upgrades, the P365 is a highly-capable, aesthetically-pleasing, and reliable 9mm pistol. That said, you can certainly take it to the next level by upgrading one or more anatomical aspects of the gun.
