Californiagunshop is a San Antonio, TX-based retailer specializing in precision firearms and tactical gear. The P320-SPECTRE COMP is a factory-built competition-ready pistol featuring an integrated compensator and optics-ready slide. This model delivers flatter shooting and faster follow-ups directly from SIG Sauer. It’s in stock now for $1250.16, a significant saving from the regular $1399.99.

Why the P320-SPECTRE COMP Belongs in Your Range Bag

Having built and tuned countless P320s for competition and duty, I can tell you the SPECTRE COMP is special. SIG didn’t just slap a comp on a slide; they engineered a system. The slide’s integrated ports work with the barrel’s crown to manage recoil impulse efficiently. This isn’t a gimmick—it’s a tangible difference you’ll feel on the timer. The first time I ran one in a local steel challenge, the reduced muzzle flip on transitions was immediately apparent. For families I coach, this controllability translates to faster, more confident shooting for all skill levels.

The Good and The Honest Trade-Offs

What You’ll Love:

  • Integrated Comp System: Not an add-on. The slide and barrel are designed together, reducing felt recoil and muzzle rise significantly.
  • Optics-Ready from the Start: The P320 spectre comp optic footprint accepts Romeo1Pro and DPP patterns, a major advantage for competition shooters.
  • Spectre Blackout Aesthetics: The sleek, all-black P320-spectre comp blackout finish isn’t just for looks—it’s a durable DLC coating.
  • Superior Trigger: Features the flat-faced SIG skeletonized trigger with a clean, predictable break.
  • Full Modularity: It’s still a P320. Swap grip modules, calibers, and sizes to your heart’s content.

Points to Consider:

  • Holster Selection: The compensator means some standard P320 holsters won’t fit. You’ll need a P320 spectre comp holster with an open end or specific channel. We carry compatible options.
  • Premium Price: It commands more than a base P320. The value is in the complete, warrantied performance package.
  • Maintenance Attention: The comp ports can carbon up. A simple extra step in cleaning keeps it running smoothly (see FAQ).

Who This Pistol Is For (And Who Might Look Elsewhere)

Buy the P320-SPECTRE COMP if:

  • You’re a competitive shooter in USPSA Carry Optics or Limited Optics looking for a box-stock advantage.
  • You want the performance of a comped pistol without the hassle and cost of aftermarket gunsmithing.
  • You’re a seasoned shooter who appreciates SIG’s engineering and wants a top-tier, modular handgun.
  • You’re building a home-defense or duty pistol where controllability for fast, accurate follow-up shots is critical.

Consider another option if:

  • Your primary need is deep concealment. The comp adds length. Check our subcompact models.
  • You’re on a very tight budget and don’t mind building over time. A standard P320 X-Series is a great starting point.
  • You compete in divisions that prohibit compensators (like USPSA Production). The standard P320 X5 Legion might be a better fit for that rule set.

Common Questions & Concerns

“Is the compensator really effective?” Absolutely. In side-by-side drills, the difference in muzzle return is noticeable. It doesn’t eliminate recoil, but it manages it upward, keeping the sights flatter. This is the core benefit in any P320 spectre comp review you’ll find.

“P320 spectre comp vs x5 legion—which for competition?” Great debate. The X5 Legion is heavier (tungsten-infused grip) and fantastic for recoil management via mass. The SPECTRE COMP uses gas redirection. The Legion is Production-legal; the SPECTRE COMP is for Carry Optics/Limited. Try both if you can; it’s a feel preference.

Frequently Asked Questions

How do I clean the Sig P320 Spectre Comp?

Focus on the compensator ports. After field-stripping, use a nylon brush and solvent to break up carbon in the slide’s top ports. A pipe cleaner works well for the barrel crown. Avoid metal picks that could damage the DLC coating. Clean as you would any P320, just give those ports a little extra attention every few range trips.

What optics fit the P320 Spectre Comp?

The slide is cut for the Sig Sauer Romeo1Pro and Leupold DeltaPoint Pro footprint. For other optics like Trijicon RMR or Holosun 507C, you will need an adapter plate, which are widely available. Ensure any plate is rated for pistol slide use.

Does it come with night sights?

Yes. It comes equipped with SIG X-RAY3 Day/Night Suppressor Height Sights. These provide a co-witness through most red dot optics and glow brightly in low light.

What holsters fit the P320 Spectre Comp?

You need a holster designed for a compensated P320 or one with an open muzzle end. Many duty-style holsters (Safariland 6390RDS) with an open channel will work. For competition, holsters from companies like GX Products or Red Hill Tactical offer specific P320 spectre comp holster models.

Is the Spectre Comp reliable for defensive use?

Yes. It uses the same proven P320 FCU (Fire Control Unit) and operating system as the U.S. Military’s M17/M18. The compensator is integral and does not introduce reliability issues with standard-pressure 9mm ammunition. Always test your chosen defensive ammo for function.
