Concealed Carry

Everyday carry that disappears on your belt

SIG P365 XL4 componentsCurrent build cost: $1,502.97Prices as of Jul 1, 2026

This is a SIG P365 XL concealed carry package built for the person who carries every day and wants a dot, a light, and a holster that actually disappears under a t-shirt. The P365 XL runs 12+1 in a grip module short enough for all-day inside-the-waistband carry, with a 3.7-inch barrel and optic-ready slide that make it easier to shoot well than the smaller base P365.

The build pairs the enclosed-emitter Holosun EPS Carry, the micro-compact Streamlight TLR-7 X Sub, an Armory Craft flat trigger, and the Tier 1 Concealed Axis Elite appendix holster. Each part is chosen so nothing on the gun fights the mission of carrying concealed: the optic and light stay slim, the trigger cleans up the pull, and the holster tucks the whole package tight to the body.

Why this build

The P365 XL is the right host because it solves the two things carriers ask for most: a factory optic cut and an accessory rail, without giving up concealment. The extended grip and 3.7-inch barrel add sight radius and velocity over the base P365 while the slide stays narrow at 1.1 inches, so it prints far less than a compact like a Glock 19. Twelve rounds flush is a real capacity advantage over single-stack micro pistols.

The Holosun EPS Carry is the load-bearing choice. Its enclosed emitter seals the LED behind glass, so pocket lint and carry debris cannot block the dot the way they can on an open-emitter optic, and that reliability is what matters on a gun you bet your life on. It weighs 1.23 oz, runs 50,000 hours on a side-loading CR1620, and ships with an RMSc-to-K adapter so it drops onto the P365 XL cut. The Streamlight TLR-7 X Sub is purpose-built for the P365's slim rail, putting 725 lumens and 7,700 candela in a light that sits flush instead of hanging past the dust cover.

The Tier 1 Axis Elite ties it together. Its shock-cord hinge lets the holster and spare-mag caddy flex independently against the body, which is why an appendix sidecar this capable still conceals; retention, ride height, and cant all adjust, and it is cut for light-bearing guns. This is a build where every piece is sized for concealment first, not adapted from a duty setup.

Pistol Lights

Streamlight TLR-7 X Sub

$159.99 at Optics Planet · In stock

The Streamlight TLR-7 X Sub is built specifically for micro-compact slim rails like the P365 XL, so it mounts flush instead of extending past the dust cover the way a full-size light would. It puts out 725 lumens and 7,700 candela with a 176-meter beam and runs on either a CR123A or the rechargeable SL-B9, giving positive target identification without wrecking concealment.

Pistol Triggers

Armory Craft Flat Trigger P365

$99.00 MSRP

The Armory Craft flat trigger swaps the P365's curved factory shoe for a flat face that improves finger placement and gives a more consistent, straight-back press. It is a low-cost, drop-in refinement that sharpens the trigger feel without altering the P365's striker safety system.

Holsters

Tier 1 Concealed Axis Elite

$144.99 MSRP

The Tier 1 Concealed Axis Elite is an appendix sidecar with a shock-cord hinge that lets the holster and integrated mag caddy flex independently, so it curves to the body and conceals better than a rigid sidecar. Retention, ride height, and cant all adjust, and it is cut for light-bearing pistols, so it clears the mounted TLR-7 Sub.

Frequently Asked Questions

▶Is the SIG P365 XL a good gun for concealed carry?

Yes. The P365 XL carries 12+1 rounds of 9mm in a package just 1.1 inches wide and about 20.7 oz with an empty magazine, so it conceals like a micro-compact but shoots like a larger gun thanks to its 3.7-inch barrel and longer sight radius. Its factory optic cut and accessory rail let you add a red dot and light, which most single-stack micro pistols cannot accept.

▶Do I need an enclosed emitter red dot for carry?

An enclosed emitter like the Holosun EPS Carry is the safer choice for concealed carry because sealed glass keeps pocket lint, sweat, and debris off the LED, so the dot cannot be blocked when you draw. Open-emitter optics like the Holosun 507K X2 work well and cost less, but they leave the emitter exposed to the carry environment.

▶What light fits the P365 XL rail?

The P365 XL uses a slim micro-compact rail, so you need a light built for it. The Streamlight TLR-7 X Sub mounts flush and delivers 725 lumens, while the SureFire XSC-P365 is purpose-made for the P365 at 350 lumens. Full-size lights like the TLR-1 do not fit the P365's slim rail.

▶Will the Holosun EPS Carry co-witness with the P365 XL sights?

The P365 XL ships with XRAY3 day/night sights, and the EPS Carry sits low enough on the slide that you can still use the factory irons as a backup, though a full co-witness depends on sight height. For a cleaner lower-third co-witness, many carriers add suppressor-height sights when they mount the optic.

▶How much does a complete P365 XL carry setup cost?

The P365 XL itself, plus the Holosun EPS Carry, Streamlight TLR-7 X Sub, Armory Craft flat trigger, and Tier 1 Axis Elite holster, comes to roughly double the price of the bare pistol as configured. You can lower the total by choosing the Holosun 507K X2 and the Rounded Gear holster; the parts list shows a live price for every component so you can see the total update as you swap.
