Key Features
- X-Series Grip Module – The high-bore-axis grip reduces muzzle flip and keeps your follow-up shots fast. Why it matters: You’ll stay on target through the 10mm recoil impulse, especially with hot loads.
- Optic-Ready Slide with Front and Rear Serrations – The slide is pre-milled for popular red dots, and the aggressive serrations let you manipulate the slide from any angle. Why it matters: No machining cost, and you can rack the slide one-handed if needed.
- XRAY3 Day/Night Sights – Tritium front and rear with a bright green ring for low-light acquisition. Why it matters: You get a visible sight picture in total darkness without batteries.
- Manual Safety – A factory-installed thumb safety on the fire control unit adds an extra layer of carry security. Why it matters: If you prefer a manual safety for holstering or administrative handling, it’s there without aftermarket modification.
- 5″ Bull Barrel – The heavy-profile barrel improves accuracy and reduces felt recoil. Why it matters: You’ll get tighter groups at distance and a smoother shooting experience.
Who It’s For
This pistol is for the daily carrier who wants 10mm power without giving up ergonomics or reliability. It’s also a solid choice for hunters, hikers, and outdoor enthusiasts who need a sidearm that can handle bear country or large game. If you’re looking for a range gun that can double as a defensive tool, the XTen fits that role.
Pros & Cons
- Pro: Factory manual safety on a proven P320 platform – no aftermarket tinkering needed.
- Pro: Optic-ready from the factory with co-witness capable XRAY3 sights.
- Con: The 10-round magazine capacity is limited compared to 15+ round 9mm options, but that’s standard for 10mm.
- Con: The grip module is larger than standard P320 grips, which may not fit smaller hands without an aftermarket module swap.
Comparison: SIG P320 XTen vs. Glock 20 Gen5 vs. Smith & Wesson M&P 10mm
| Feature | SIG P320 XTen | Glock 20 Gen5 | S&W M&P 10mm |
|---|---|---|---|
| Caliber | 10mm Auto | 10mm Auto | 10mm Auto |
| Barrel Length | 5″ bull barrel | 4.61″ | 4.6″ |
| Optic Ready | Yes (RMSc/DeltaPoint Pro) | MOS (optional) | Yes (CORE) |
| Manual Safety | Factory-installed | Not available | Optional (some SKUs) |
| Weight (unloaded) | 33.5 oz | 30.7 oz | 33.6 oz |
| Capacity | 10 rounds | 15 rounds | 15 rounds |
The Glock 20 offers higher capacity but lacks a manual safety. The M&P 10mm is close in weight but has a shorter barrel. The SIG P320 XTen stands out with its bull barrel accuracy and factory safety option.
Is the SIG P320 XTen 10mm optic-ready slide compatible with all red dots?
It fits most RMSc and DeltaPoint Pro footprint optics. Per SIG SAUER specs, you’ll need a mounting plate for some models, but the slide is pre-tapped for direct mounting.
Does the manual safety affect holster compatibility?
Most P320 holsters that are cut for a safety lever will work. Check holster listings for “manual safety” compatibility – many brands offer a specific cut.
Can I use the 15-round P320 magazines in the XTen?
No – the XTen uses proprietary 10mm magazines. Standard P320 9mm/.357 SIG/.40 S&W magazines will not fit.
Is the XTen suitable for concealed carry?
It’s a full-size pistol, so it’s best for OWB or winter carry. With the right holster and belt, some shooters do carry it AIWB, but it’s not a compact option.
