Description
The SIG SAUER P320 Full Tacpro 9mm Nit 10+1 is a striker-fired, full-size pistol built for daily carriers who want modularity and reliability out of the box. This model pairs a 4.7-inch barrel with a nitron-coated stainless steel slide and a 10-round magazine, giving you the full-size grip and sight radius without the bulk of a duty gun. It’s the same platform used by the U.S. military as the M17/M18, and at this price point, it’s a solid entry into the P320 ecosystem.

Key Features
- Full-Size Grip Module — The longer grip gives you a full four-finger hold, which means better recoil control and faster follow-up shots during range sessions or defensive drills.
- Nitron Finish — SIG’s proprietary nitron coating resists holster wear, sweat, and moisture. It’s not just a cosmetic upgrade; it’s a durability feature for daily carry and training.
- 10+1 Capacity — At ten rounds in the magazine plus one in the chamber, you’re compliant with most magazine-restricted states while still having enough firepower for personal defense.
- Striker-Fired Trigger — The P320’s trigger breaks cleanly at around 5.5 to 6.5 pounds (per SIG SAUER specs), with a short reset that makes fast, accurate strings easier to manage.
- Modular Fire Control Unit — The serialized FCU lets you swap grip modules, slides, and calibers without needing a new transfer. That’s one gun that can grow with you.
Who It’s For
This SIG SAUER P320 Full Tacpro is for the EDC enthusiast who wants a full-size frame for range use and home defense but needs a 10-round magazine for state compliance. It’s also for anyone looking to start building a P320 modular system on a budget—the Tacpro gives you the core platform without the premium price tag of a custom shop gun. If you’re a left-handed shooter, the ambidextrous slide catch makes this a natural fit.
Pros / Cons
- Pro: Modular FCU means you can upgrade to a compact grip or a 9mm conversion kit later without buying a whole new firearm.
- Pro: The 4.7-inch barrel gives you a longer sight radius than compact models, which helps with accuracy at 15 to 25 yards.
- Con: The factory trigger has a bit of take-up before the wall. It’s not gritty, but shooters used to aftermarket triggers may want to swap in a flat trigger shoe for a more consistent pull.
- Pro: Nitron finish holds up well against daily holster wear—I’ve seen P320s with thousands of draws that still look clean.
- Con: The full-size grip can print under lighter clothing, so it’s better suited for OWB carry or winter EDC setups.

The Zev and Agency options are premium builds with tighter tolerances and lighter triggers, but the P320 Full Tacpro gives you 90% of the functionality at less than half the price. For most daily carriers, the SIG’s modularity and reliability make it the better value.
FAQ
Is the SIG SAUER P320 Full Tacpro compatible with standard P320 holsters?
Yes. The Full Tacpro uses the same frame dimensions as the standard P320 full-size, so any holster designed for a P320 full-size with a 4.7-inch barrel will work. Just confirm your holster is cut for the accessory rail (MIL-STD-1913).
Can I use this pistol for concealed carry?
You can, but it’s better suited for OWB or winter carry due to the full-size grip length. If you want to carry it IWB, look for a holster with a wedge or claw to reduce printing. Many users swap to a compact grip module for CCW.
What magazines are compatible with the P320 Full Tacpro?
Any SIG SAUER P320 9mm magazine that fits the full-size grip module works—standard 17-round, 21-round, or the 10-round magazine that comes with the gun. Magazines from the M17 or M18 are also cross-compatible.
Does this model come optics-ready?
No, the Full Tacpro does not include a factory optics cut. You’ll need to send the slide to a machine shop for a red dot cut, or swap to an optics-ready P320 slide later. The slide is standard stainless steel with dovetail sights.
