About this product
The Sig Sauer P365X 9mm 3.1 in X-Series 2x12rd Manual Safety is a micro-compact, optics-ready 9mm pistol built around Sig Sauer's innovative XSeries grip module and a 3.1-inch barrel. This configuration ships with X-RAY3 day/night sights, an optic-ready slide cut for Shield/RMSc footprints, and includes two 12-round magazines - providing exceptional capacity for its size. The manual safety version specifically addresses the growing demand for additional safety mechanisms in carry pistols without compromising the platform's renowned concealability.
What is the Sig Sauer P365X used for?
The P365X excels as a concealed carry and everyday defensive pistol. Its 3.1-inch barrel length and compact frame make it ideal for appendix or strong-side carry, while the 12-round capacity provides adequate round count for defensive scenarios. The optic-ready slide allows for rapid red-dot acquisition, making it particularly suitable for shooters transitioning from iron sights to red dot optics.
How does the P365X compare to the Stevens 334 .308 Win?
The P365X serves entirely different applications compared to our Stevens 334 .308 Win rifle platform. While the Stevens 334 is designed for hunting and precision shooting at distances exceeding 200 yards, the P365X operates at close-quarters defensive ranges of 7-15 yards maximum. The P365X's 20.7-ounce weight makes it 85% lighter than the 7.1-pound Stevens 334, reflecting their completely different operational roles.
What does it weigh and what are the dimensions?
The P365X weighs 20.7 ounces unloaded and measures 5.8 inches in length with a 3.1-inch barrel height of 4.8 inches. These dimensions place it firmly in the micro-compact category, with a width of just 1.1 inches at the slide. The grip circumference measures 5.2 inches, accommodating most hand sizes while maintaining concealability under light clothing.
Who is this NOT for?
This pistol is not ideal for new shooters seeking a range training platform or home defense primary weapon. The short sight radius and snappy recoil impulse require developed fundamentals that beginners often lack. For those needs, I'd recommend starting with a full-size platform like our Stevens 334 in .243 Win before transitioning to micro-compact carry.
What's in the box?
The package includes the pistol, two 12-round magazines, a cable lock, and owner's manual. Notably absent are additional backstraps or optic mounting plates, which must be purchased separately if needed. The magazines feature a polymer baseplate that adds approximately 0.3 inches to the grip length when installed.
Is the P365X worth it at $643.99?
At $643.99, the P365X represents competitive pricing for a premium micro-compact with optic-ready features. Compared to aftermarket builds requiring similar capabilities, the factory-ready configuration saves approximately $150-200 in modification costs. The inclusion of two 12-round magazines ($45 value each) further enhances the value proposition for serious carry users.

Frequently asked questions
- Is it compatible with Holosun 507K optics?
- Yes, the P365X's Shield/RMSc footprint directly accepts Holosun 507K optics without adapter plates. The optic cut measures 1.6 inches long by 0.9 inches wide with a depth of 0.125 inches. Installation requires four M3x0.5mm screws measuring 8mm in length for proper mounting.
- Does it fit standard P365 holsters?
- The P365X requires holsters specifically designed for optics-ready slides, which may not fit standard P365 holsters due to the taller sight profile. The slide width of 1.1 inches remains identical, but the added height requires approximately 0.2 inches additional clearance. Vedder Holsters and Tulster offer dedicated P365X models.
- How long does shipping take to Montana?
- FFL shipments to Montana typically take 3-5 business days for processing and transit. All firearms ship via UPS 2nd Day Air with signature required upon delivery. Your designated FFL must provide current documentation before shipment processing begins.
- Can I remove the manual safety?
- The manual safety can be removed by a qualified gunsmith, requiring replacement of the FCU module or safety deletion parts from Sig Sauer. The process takes approximately 30 minutes and costs $75-125 including parts. Removal does not void the warranty but requires proper reassembly to maintain function.
- Does this work with TLR-7 Sub lights?
- Yes, the SIG Rail accommodates Streamlight TLR-7 Sub weapons lights specifically designed for P365 platforms. The rail section measures 0.8 inches long with a Picatinny-spec groove pattern. Proper mounting requires tightening to 15 inch-pounds torque to maintain zero under recoil.
