Key Features
- 5" Bull Barrel — WHY IT MATTERS: The longer barrel boosts 10mm bullet velocity and sight radius for tighter groups at 25+ yards, critical for duty accuracy or hunting backup.
- Optic-Ready Slide — WHY IT MATTERS: Directly mounts popular red-dots (RMR, DPP) without adapter plates, cutting setup time and keeping co-witness with XRAY3 irons.
- XRAY3 Day/Night Sights — WHY IT MATTERS: Tritium front and rear luminescent rings ensure low-light target acquisition, a must for home defense or after-dark carry.
- XSeries Grip Module — WHY IT MATTERS: Reduced trigger reach, undercut trigger guard, and aggressive texture give you a locked-in grip for rapid follow-ups on hot 10mm loads.
- 15-Round Steel Magazines (x2) — WHY IT MATTERS: Full-capacity 10mm mags mean fewer reloads during range sessions, training, or defensive scenarios where every round counts.
Who It's For
Urban CCW holders looking for a hard-hitting home defense option that still fits a nightstand safe. Apartment dwellers who want a pistol that can stop a threat through barriers without over-penetrating like rifle rounds. Shooters stepping up from 9mm who want a flat-shooting, high-energy platform for outdoor defense or bear country carry.
Pros/Cons
- Pro: Factory optic cut saves $100+ on aftermarket milling — drop a dot and go.
- Pro: XSeries grip reduces felt recoil from 10mm by improving hand placement.
- Con: Full-size frame limits concealed carry for smaller builds — consider the P320 XTEN Compact if appendix carry is your goal.

FAQ
What red-dot footprints does the P320 XTEN slide accept?
The slide is cut for Trijicon RMR, Leupold DeltaPoint Pro, and Sig Sauer ROMEO1PRO footprints. No adapter plate required for those patterns.
Can I use standard P320 holsters with the XTEN?
Yes, most full-size P320 holsters (Safariland, Blackhawk, etc.) fit the XTEN frame and slide profile. Confirm your holster is rated for 5" barrel length.
What is the trigger pull weight?
Per Sig Sauer specs, the factory flat trigger breaks at approximately 5.5–6.5 lbs with a crisp reset.
Is this pistol suitable for concealed carry?
It's best for open carry, duty, or home defense due to the full-size grip. For CCW, consider the P320 XTEN Compact or a 9mm subcompact.
