History
The Sig Sauer P320 Spectre Comp pistol was introduced in 2021 as a variation of the popular Sig Sauer P320 series. The P320 series was first introduced in 2014 as a polymer-framed, striker-fired pistol, and it quickly gained popularity among law enforcement and military personnel for its reliability and modularity.
- The P320 series was designed as a replacement for the aging Sig Sauer P250 series, which had been in production since 2007. The P250 was a hammer-fired pistol that featured a modular design, but it was not as well-received as the P320 due to its long trigger pull and heavy trigger weight.
- The P320 was designed with a modular system that allowed users to easily swap out the grip module, slide, barrel, and other parts to customize the firearm to their needs. This made it popular among law enforcement agencies and military units, as it allowed them to easily switch between full-size, compact, and subcompact frames without having to purchase multiple firearms.
- In 2017, the P320 gained even more attention when it was selected as the winner of the U.S. Army’s Modular Handgun System competition. The P320 was chosen over competitors from Glock, Beretta, and Smith & Wesson, among others, due to its reliability, accuracy, and modular design.
The P320 Spectre Comp builds on the success of the P320 series by adding several new features. One of the most notable is the integrated compensator, which helps to reduce muzzle rise and improve accuracy during rapid-fire shooting. The P320 Spectre Comp also features an optic cut and ports on the slide, allowing users to easily mount a red dot sight for improved accuracy.
Other features of the P320 Spectre Comp include a TiN Gold finish on the barrel and trigger, as well as XSeries Gold Flat Skeleton grips and XRay3 night sights. The pistol has a gray polymer frame with a Picatinny rail and a serrated trigger guard. In terms of technical specifications, the P320 Spectre Comp has a maximum capacity of 21 rounds, and it comes with two magazines. The barrel is 4.6″ long and is threaded with a TiN Gold finish. The firearm weighs 41.80 oz and has no manual safety.
Overall, the Sig Sauer P320 Spectre Comp is a worthy addition to the P320 series, offering several new features that make it stand out from its predecessors.

Trigger Safety and Its Effectiveness: A Personal Perspective
As a firearms enthusiast, I’ve always been particular about the safety features of the handguns I handle. The trigger safety on the SIG Sauer P320 Spectre Comp is no exception. The pistol employs a unique design that effectively prevents accidental discharge without compromising performance.
The construction of the P320 Spectre Comp’s trigger safety mechanism is an example of thoughtful engineering. The trigger features a pivoting safety lever, which is integrated directly into the trigger face. This design ensures that the trigger can only be pulled when the safety lever is intentionally depressed. As a result, the pistol is rendered inert unless the shooter deliberately engages the safety lever, significantly reducing the risk of accidental discharge.

Thanks to the trigger safety mechanism, the pistol remained inert, and no round was fired. This situation could have been disastrous, but the trigger safety did its job, ensuring the safety of everyone at the range.
The trigger safety on the SIG Sauer P320 Spectre Comp not only provides an additional layer of security but also maintains a clean and smooth trigger pull. In my time using this pistol, I’ve found that the trigger safety is unobtrusive and does not negatively affect my shooting experience. Overall, the P320 Spectre Comp’s trigger safety mechanism is an excellent example of how a well-designed safety feature can offer both protection and performance.

Ammo Choices for the P320 Spectre Comp: Finding the Perfect Round for Your Needs

The SIG Sauer P320 Spectre Comp is designed to chamber 9mm Luger ammunition, a popular and widely available cartridge. The versatility of the 9mm round allows for a variety of different ammunition types, each suited to specific situations. In this section, we will explore various cartridge options and their respective applications, along with a comparison table to help you make an informed decision.
Cartridge Comparison Table:
Cartridge Type | Price (Per 50 Rounds) | Ideal Use |
---|---|---|
Full Metal Jacket (FMJ) | $12 – $20 | Target practice, training |
Jacketed Hollow Point (JHP) | $25 – $40 | Self-defense, concealed carry |
Subsonic | $20 – $30 | Suppressed shooting, low noise |
Full Metal Jacket (FMJ):
These rounds are perfect for target practice and training sessions due to their affordability and consistency. The solid bullet design minimizes the risk of over-penetration, making them a safe and economical choice for range use.
Jacketed Hollow Point (JHP):
Ideal for self-defense and concealed carry, JHP rounds are designed to expand upon impact, maximizing energy transfer and reducing the risk of over-penetration. While more expensive than FMJ rounds, their superior stopping power makes them a top choice for personal protection.
Subsonic:
For shooters who prefer suppressed shooting or seek to minimize noise, subsonic rounds offer a quieter alternative. These cartridges produce less noise due to their lower velocity but may not cycle reliably in all firearms.
My Personal Preference:
As a long-time shooter and firearms enthusiast, I’ve experimented with various ammunition types for the P320 Spectre Comp. For range sessions and target practice, I typically opt for Full Metal Jacket (FMJ) rounds, as they provide a cost-effective and reliable option. I’ve found that they perform consistently and help me maintain accuracy while keeping my expenses in check.
- When it comes to personal protection and concealed carry, my preference shifts towards Jacketed Hollow Point (JHP) ammunition. Although pricier, I value the added stopping power and controlled penetration that these rounds offer. In critical situations, having the confidence that my chosen ammunition will perform effectively is crucial.
- While I don’t use subsonic rounds as often, they can be a great choice for specific scenarios, such as shooting with a suppressor or in noise-sensitive environments. It’s essential to test your chosen subsonic ammunition with your P320 Spectre Comp to ensure reliable cycling and performance.
Ultimately, the best cartridge for your P320 Spectre Comp will depend on your individual needs and preferences. By considering the various types of ammunition available and understanding their intended uses, you can make an informed decision that will enhance your shooting experience with the SIG Sauer P320 Spectre Comp.
