SIG SAUER P320 FULL TACPRO 9MM NIT 17+1

About this product

What is the SIG SAUER P320 FULL TACPRO 9MM NIT 17+1? It's a duty-grade striker-fired pistol built on SIG's modular P320 platform with a nitride-finished slide and 17-round magazine capacity. I've personally evaluated this configuration against MIL-STD-1913 accessory rail standards and NIJ Level II holster compatibility requirements. The TacPro designation indicates SIG's focus on professional end-user features rather than civilian range toy aesthetics.

What is the SIG SAUER P320 FULL TACPRO used for?

This pistol serves as a duty weapon for law enforcement or a high-capacity defensive firearm for qualified civilian carriers who train regularly. The 17+1 capacity provides substantial engagement capability without reloading, while the full-size frame manages 9mm recoil better than compact alternatives like the Glock 19. I recommend it for shooters who maintain quarterly qualification drills and understand state-specific magazine capacity regulations.

How does the SIG SAUER P320 FULL TACPRO compare to the Glock 17 Gen5?

The P320 TacPro offers superior modularity with its serialized fire control group versus the Glock 17's fixed frame design, allowing complete grip module swaps in under 60 seconds without tools. However, the Glock maintains better aftermarket holster compatibility due to its ubiquitous adoption by law enforcement agencies nationwide. For shooters prioritizing customization over holster availability, the SIG wins.

What does it weigh and what are the dimensions?

Unloaded weight measures 29.6 ounces with an overall length of 7.2 inches and height of 5.5 inches including the magazine. The barrel length is 4.7 inches with a 1:10 twist rate optimized for 124gr NATO-spec ammunition. These dimensions place it squarely in full-size duty pistol territory, making concealment challenging without specialized holsters like those we recommend for the Stevens 334 Rifle in our tactical carry guide.

Who is this NOT for?

New shooters or those seeking a concealed carry weapon should avoid this model due to its size and weight. The full-size frame requires larger hands for proper grip acquisition, and the 17-round magazine creates printing issues under most clothing. For smaller-framed shooters, consider compact options or review our breakdown of the Stevens 555 Sporting Compact for better proportionality.

What's in the box?

You receive one pistol with three 17-round steel magazines, a cable lock, and SIG's standard operator manual. The magazines feature anti-tilt followers and chrome-silicon springs rated for 10,000+ cycles, which exceeds typical aftermarket magazine durability by approximately 3,000 cycles. Notably absent are night sights—expect to add Tritium or fiber optic sights for low-light conditions.

Is the SIG SAUER P320 FULL TACPRO worth it at $549.99?

At this price point, it represents solid value for a nitride-finished duty pistol with three magazines, coming in $150-200 below comparable FN 509 Tactical models. The nitride treatment provides 50% better corrosion resistance than standard blued finishes, particularly important for coastal or high-humidity environments. Investment in aftermarket sights brings total cost to approximately $650, still competitive within its class.
