Description
The Sig Sauer P365 XMacro Handgun 9mm Luger 17rd Magazines (2) 3.7″ Barrel Two Tone Green TB with Optic is a factory-built concealed carry powerhouse that pairs a threaded barrel with an optics-ready slide. This setup delivers suppressor-ready capability and a crisp red dot sight mount out of the box, using the same 17-round flush-fit magazine platform that made the XMacro a top seller. You get two magazines, a two-tone green finish, and a pre-installed optic, all ready to run from the case.

Key Features
- Factory-Installed Optic – The slide comes with a pre-mounted Sig Sauer Romeo Zero or similar micro red dot, saving you the cost and hassle of buying and installing an optic separately. You get a co-witnessed sight picture for immediate accuracy.
- Threaded Barrel (TB) – The 3.7″ barrel has factory threads (1/2×28) for attaching a suppressor or compensator. This means you can run a can on a compact frame without a custom barrel purchase.
- Two 17-Round Magazines – Each flush-fit magazine holds 17+1 rounds of 9mm Luger, giving you a full-size capacity in a subcompact grip. That’s a 50% capacity increase over the original P365 without adding bulk.
- Two-Tone Green Finish – The green slide coating is a durable PVD finish that resists holster wear and corrosion. It also breaks up the visual profile of the gun, which some shooters prefer for low-light or tactical use.
- XSeries Trigger and Grip – The flat XSeries trigger has a clean 4.5-5.0 lb break with a short reset, and the integrated compensator slide cuts reduce muzzle flip. The grip module includes an integrated magwell for faster reloads.
Who It’s For
This is for the shooter who wants a single gun that does double duty as a daily carry and a home-defense pistol. It’s ideal if you plan to run a suppressor or compensator without buying a second barrel. It also fits anyone who wants an optics-ready gun right out of the box, without sending the slide to a machine shop.
Pros / Cons
- Pro: 17-round capacity in a frame that conceals like a single-stack. Per Sig Sauer specs, the XMacro grip is only 1.0” wide.
- Pro: Threaded barrel is included at no extra cost vs. the standard model, saving you $80-120 on aftermarket barrels.
- Con: The two-tone green finish is not available in all-black, which may not appeal to shooters who want a uniform dark gun. You can cerakote it later, but that adds cost.
- Con: The pre-installed optic is a 3-MOA dot, which some shooters find too small for fast close-range target acquisition. You can swap it, but that eats into the value.
Comparison
| Feature | Sig P365 XMacro TB w/ Optic | Zev Technologies OZ9c | Glock 43X MOS |
|---|---|---|---|
| Caliber | 9mm Luger | 9mm Luger | 9mm Luger |
| Capacity | 17+1 | 15+1 | 10+1 |
| Barrel Length | 3.7” (threaded) | 4.0” | 3.41” |
| Optic Ready | Yes (pre-installed) | Yes (RMSc pattern) | Yes (MOS, plate required) |
| Weight (unloaded) | 20.0 oz | 22.5 oz | 18.7 oz |
| MSRP | $1,108.94 | $1,299.00 | $579.00 |
The XMacro beats the Zev OZ9c in capacity and price, while the Glock 43X MOS is lighter but holds seven fewer rounds and lacks a threaded barrel. For the money, the Sig packs more features per dollar than either competitor.
FAQ
Does the P365 XMacro TB with optic come with suppressor-height sights?
Yes. The factory slide includes tall suppressor-height night sights (front and rear) that co-witness through the Romeo Zero optic. You can use them as backup irons if the dot fails.
Can I use standard P365 magazines in the XMacro?
Yes and no. Standard P365 10- and 12-round magazines will lock into the XMacro grip, but they leave a gap at the base. For reliable feeding and a flush fit, use the included 17-round XMacro magazines. The 15-round P365X magazines also work but sit slightly proud.
Is the threaded barrel compatible with most 9mm suppressors?
Yes. The barrel is threaded 1/2×28, which is the standard pitch for 9mm suppressors like the SilencerCo Omega 9K, Dead Air Wolfman, and Rugged Obsidian 9. You just need a piston mount for the suppressor to attach to the barrel.
What optic footprint does the slide use?
The slide is cut for the Sig Sauer Romeo Zero footprint, which is the same as the JPoint and Shield RMSc pattern. You can mount optics from Holosun (K series), Swampfox, and others with an adapter plate, but the Romeo Zero is included and ready to go.
