SIG SAUER P320 SNAKEBITE TACOPS 9MM 21+1
About this product
The SIG SAUER P320 SNAKEBITE TACOPS 9MM 21+1 is a duty-oriented variant of the P320 platform engineered for out-of-the-box tactical performance, featuring a flat trigger, suppressor-height sights, and 21-round magazines. This isn't a casual range toy — it's a professional-grade semi-automatic pistol built on SIG's modular FCU system. The 'Snakebite' name references its flat dark earth PVD coating and specialized components for immediate accessory compatibility.
What is the SIG SAUER P320 SNAKEBITE TACOPS 9MM used for?
This pistol is built for high-round-count duty, competition, and prepared home defense roles where magazine capacity and accessory mounting are priorities. Its primary use case is for shooters who need a reliable, high-capacity 9mm that accepts optics and suppressors without modification. The included 21-round magazines and optics-ready slide make it ready for a red dot and white light out of the box.
How does the SIG SAUER P320 SNAKEBITE TACOPS compare to a Glock 17 Gen5 MOS?
The P320 Snakebite is better for modular customization, while the Glock 17 retains an edge in total aftermarket holster support. The key mechanical difference is the P320's serialized Fire Control Unit (FCU), which allows you to change grip modules in under 3 minutes versus the Glock's permanent frame integration. For shooters who value a modular platform or prefer a flat trigger pull set at a crisp 4.5 lbs, the SIG is the superior choice.
What does it weigh and what are the dimensions?
Unloaded, the pistol weighs 32.4 ounces with the standard polymer grip module, measuring 8 inches in overall length with a 4.7-inch threaded barrel. The height is 5.5 inches to the top of the suppressor-height sights, and the slide width is 1.3 inches. A loaded 21-round magazine of 9mm adds approximately 14 ounces.
Who is this NOT for?
This is a poor choice for first-time firearm owners or concealed carry permit holders seeking a discreet daily carry pistol. Its extended magazines and threaded barrel make concealment impractical compared to compact models like our Stevens 334 in .308 Win for hunting roles. If your primary need is a simple, low-maintenance firearm for occasional range use, the complexity and components are overkill.
What's in the box?
The package includes the pistol, two 21-round steel magazines, an optics cover plate, a cable lock, and the standard SIG case with foam cutouts. Unlike base P320 models, this Tacops variant ships with four sealing plate options for common red dot footprints (Deltapoint Pro, RMR, Romeo1Pro, Leupold) and suppressor-height X-RAY3 day/night sights pre-installed. You will not receive a cleaning kit or complementary holster.
Is the SIG SAUER P320 SNAKEBITE TACOPS worth it at $580.99?
Yes, at $580.99 this represents a $150-200 value over building a comparable P320 from aftermarket parts due to the included magazines and specialized sights. The two 21-round magazines alone retail for $50 each, making the premium for the Tacops configuration justifiable for its intended role. When you consider it's ready for a suppressor and optic immediately, it avoids the common $300+ in upgrades required for a standard model.

Pros & cons
What works
- Includes two 21-round steel magazines — a $100 value over standard 17-round capacity
- Flat XSeries trigger breaks at 4.5 lbs — 1.5 lbs lighter and crisper than the standard P320
- Pre-installed suppressor-height X-RAY3 night sights with a .365" front sight width for precise alignment
- Optics-ready slide with four sealing plates covers DPP, R1P, and RMR footprints immediately
Trade-offs
- Threaded barrel adds 0.6 inches to overall length — holster compatibility is severely limited versus non-threaded barrels
- Flat Dark Earth PVD coating shows holster wear more visibly than Nitron or Cerakote finishes
- No manual safety model available — the FCU is configured for a trigger-safety-only operation
- Full-size grip module may be too large for shooters with medium or small hands without purchasing a separate $45-70 module

Frequently asked questions
- Is it compatible with Holosun 507C red dot sights?
- Direct mount compatibility requires the SIG Sauer ROMEO1PRO footprint. To mount a Holosun 507C, which uses the Trijicon RMR pattern, you will need a CHPWS or Springer Precision adapter plate sold separately for $65-$90. The included sealing plates cover the DPP, R1P, and RMR patterns with appropriate screws.
- Does it fit in standard SIG P320 full-size holsters?
- No, the suppressor-height sights, 4.7-inch threaded barrel, and possible mounted optic will cause standard holsters to fail. You need a holster specifically designed for the P320 XFull/Tacops with an open muzzle end and optic channel, like offerings from Tier 1 Concealed or Safariland's 6390RDS series.
- How long does shipping take to an FFL?
- Processing and shipping take 2-4 business days for in-stock items. Once shipped, transit to your selected FFL dealer typically adds 3-7 business days depending on carrier and destination. Federal law requires shipment only to a licensed dealer who will conduct the mandatory NICS background check upon your arrival.
- Can I return it if it doesn't fit my hand?
- No. Due to federal firearms regulations, Ironclad Armory cannot accept returns on serialized firearms once the transfer to your FFL is initiated. We suggest handling a standard P320 grip module at a local dealer first. The FCU can be installed into smaller grip modules like the Wilson Combat Compact, sold separately for $65.
