Description
The SIG SAUER P320 FULL TACPRO 9MM NIT 17+1 is a factory-built, full-size pistol designed for shooters who want a ready-to-run setup without aftermarket guesswork.

Key Features
- Threaded Barrel (4.7 inches) – WHY IT MATTERS: You can attach a suppressor or compensator without sending the barrel out for threading. Saves you $150–$200 in gunsmith fees.
- Suppressor-Height Night Sights – WHY IT MATTERS: Co-witness with a red dot or see your sights over a suppressor. No need to buy aftermarket irons.
- Optics-Ready Slide – WHY IT MATTERS: The slide is pre-cut for popular reflex sights (e.g., Romeo1Pro, Delta Point Pro). You can mount a dot in minutes with the included adapter plates.
- 17+1 Round Capacity – WHY IT MATTERS: You get a full-size grip with enough ammo for most defensive scenarios. Extra magazines are widely available and affordable.
- Striker-Fired Trigger with 5.5–6.5 lb Pull – WHY IT MATTERS: The trigger is consistent and predictable, with a short reset that helps you shoot faster without sacrificing safety.
Who It’s For
This pistol is built for the shooter who wants a do-it-all full-size handgun: home defense, range practice, and even suppressed shooting. It’s especially good for new gun owners who don’t want to buy a stock pistol and then spend another $400 on upgrades. The TACPRO comes ready for optics and suppressors right out of the box, so you can focus on learning the fundamentals.
Pros & Cons
- Pros: Factory-threaded barrel saves you a gunsmith trip; suppressor-height sights included; optics-ready slide; reasonable price for a fully featured pistol; reliable SIG SAUER build quality.
- Cons: The grip module is a bit chunky for shooters with smaller hands—you may want to swap it for an X-Series or Wilson Combat grip (about $50). Also, the slide does not come with a cover plate for the optics cut, so you’ll need to buy one if you don’t mount a dot right away.

The TACPRO gives you 90% of the features of a custom pistol at half the price. The Zev and Agency guns are lighter and have better triggers, but you’re paying $750–$950 more for marginal gains. For most shooters, the SIG is the smarter buy.
FAQ
Does the SIG SAUER P320 FULL TACPRO come with suppressor-height sights?
Yes. The TACPRO model includes SIG SAUER’s suppressor-height night sights (steel, three-dot tritium). They co-witness with most red dot sights and let you see over a suppressor.
What optics fit the P320 TACPRO slide?
The slide is cut for SIG SAUER’s PRO footprint (Romeo1Pro, Romeo2, Delta Point Pro). It also includes adapter plates for other common footprints. Check the manual to confirm plate compatibility with your specific dot.
Can I use standard P320 holsters with the TACPRO?
Most full-size P320 holsters will work, but you need one that accommodates the threaded barrel and suppressor-height sights. Many holster makers (e.g., Safariland, Blackhawk) have TACPRO-specific options.
Is the barrel 1/2×28 threaded?
Yes. The barrel is 4.7 inches with 1/2×28 threads, which fits the vast majority of 9mm suppressors and compensators.
How does the trigger compare to a standard P320?
It’s the same fire-control unit as other P320s, so the trigger pull weight and feel are identical—5.5 to 6.5 pounds with a crisp break and short reset. If you want a lighter trigger, you can swap the FCU or install a Timney aftermarket trigger.
