Key Features

• Threaded, Gold-Finished Barrel (4.3″) — Why it matters: Lets you mount a suppressor or compensator without swapping barrels, and the gold coating adds corrosion resistance plus a clean look.
• Optic-Ready Slide — Why it matters: You can mount most popular micro red dots directly, no milling or adapter plates needed, for faster target acquisition.
• XRAY3 Day/Night Sights — Why it matters: Tritium front and rear give you a visible aiming reference in low light, and the bright front ring stands out against dark targets.
• 17-Round Capacity (Two Magazines Included) — Why it matters: You get 17+1 rounds in a frame that’s still compact enough for daily carry — more firepower than most subcompacts without the grip length of a full-size.
• Shark Coast Tactical Sand Cerakote Frame — Why it matters: The durable, low-glare finish resists holster wear and sweat, and the sand color reduces glare in bright conditions.

Who It’s For

This pistol is for the everyday carrier who wants suppressor capability without stepping up to a duty-sized gun. It also fits shooters who like modular setups — you can swap grips, slides, and optics to dial in your perfect fit. New gun owners will appreciate the easy controls and the fact that it runs on standard P365 magazines (with adapters). If you train with a red dot or plan to, the optic-ready slide saves you time and money.

Pros & Cons

• Pro: Threaded barrel is factory-installed, so you don’t need a gunsmith or extra parts to run a suppressor.
• Pro: The 17-round magazine gives you near-full-size capacity in a package that conceals well.
• Con: The gold barrel is eye-catching, which may not appeal to everyone who prefers a low-visibility setup.
• Con: Being a compact platform, the grip may feel short for shooters with larger hands — an extended magazine basepad helps.

The XMACRO beats both on price and capacity per ounce. The Zev OZ9 has a metal frame, which adds weight but also cost. The Agency Syndicate is built around a similar threaded-barrel concept but runs about $300 more. For a suppressor-ready compact, the XMACRO gives you the most value out of the box.

FAQ

Does the Sig Sauer P365 XMACRO accept standard P365 magazines?

Yes, but with a catch. Standard 10-, 12-, and 15-round P365 magazines will lock into the XMACRO frame, but the grip has a longer dust cover. You’ll need a grip adapter or a magazine with a basepad that fills the gap. The included 17-round magazines are flush-fit.

Can I mount a suppressor directly to this barrel?

Yes. The barrel has a standard 1/2×28 thread pitch, which fits most 9mm suppressors. You don’t need a piston if the suppressor is direct-thread, but for tilting-barrel operation, a Nielsen device (piston) is recommended to prevent cycling issues.

Is the optic cut compatible with the Holosun 507K?

Yes. The slide is cut for the Shield RMSc footprint, which also fits the Holosun 507K, 407K, and EPS Carry. It’s a direct mount — no adapter plate needed.

What holsters work with the XMACRO threaded barrel?

Most P365 XMACRO holsters will work, but you need one with an open muzzle or a threaded-barrel channel. Brands like Tier 1 Concealed, Vedder, and Blackpoint Tactical make specific options. Check the holster description for “threaded barrel” compatibility.
