Sig Sauer P365 365Xf9Bfo 9Mm 4.3 Or 17/21R

The Sig Sauer P365-XMACRO (also called the 365Xf9Bfo) is a striker-fired 9mm compact pistol that bridges the gap between concealment and shootability—offering full-size ergonomics and capacity in a frame thin enough for everyday carry. Built on the proven P365 platform, the XMACRO delivers 21+1 round capacity with a 4.3-inch barrel and a sight radius of 6 inches, giving you the sight picture and control of a full-size duty gun without the bulk. At just 1.1 inches wide and 23.1 ounces, it's the kind of pistol you'll actually carry rather than leave behind.

The aggressive serrated slide is cut for optics (Shield RMS-c footprint) and pairs with a crisp nickel-plated flat-faced trigger and fiber-optic front sight for fast, accurate target acquisition in any light. The LXG grip module features laser-stippled texture for a secure grip in wet conditions, and the removable magwell improves magazine changes under pressure. Three interchangeable backstraps let you dial in the fit for your hand, while the M1913 accessory rail accepts lights and lasers. The carbon steel barrel wears a durable DLC finish, and the stainless steel slide and frame are finished in Nitron for corrosion resistance.

Box contents include two 21-round steel magazines and one 17-round magazine—flexibility for carry, duty, or range work. No manual safety means consistent trigger access, and the striker action is inherently reliable. Whether you're carrying concealed, heading to the range, or training for defensive proficiency, the XMACRO doesn't ask you to compromise.

Frequently Asked Questions

Can the P365-XMACRO accept a red-dot optic?

Yes. The slide is optics-ready and cut for the Shield RMS-c footprint. You'll need a compatible optic and mounting plate; the pistol ships without an optic installed.

What's the difference between the included magazines?

You get two 21-round magazines (the standard capacity for this platform) and one 17-round magazine. The 17-rounder is useful for carry if you want a smaller profile or as a backup. All three are steel construction.

Is this pistol suitable for concealed carry?

Yes. At 1.1 inches wide and 23.1 ounces, the XMACRO is designed to balance carry comfort with the shootability of a larger frame. Its thin grip module and compact profile make it concealable in most carry methods, though its full-size sight radius and 4.3-inch barrel give you the handling of a duty-size gun.

Does it have an external safety?

No. The P365-XMACRO has no manual safety and relies on the striker-fired mechanism. The trigger is consistent and clean, favoring fast, reliable access in a self-defense scenario.
