SSS.6.162 - Combat Application Technologies CAT/SC/B1 and the HK P30L

The CAT/SC/B1 (CAT SC) is a lightweight, highly advanced, and modular centerfire pistol silencer that exhibits extreme sound signature suppression performance for both operators and bystanders. The silencer’s combined performance, flow rate, and modularity, represent the most significant advancement in centerfire 9mm pistol suppression in recent history. The CAT SB-SHOCK technology, adapting characteristics from both SURGE BYPASS and DiVerge, results in maximizing performance in relatively small design envelopes; a significant benefit in suppressed handgun applications.

In this review, the CAT SC performance metrics depend upon suppressing a full-size handgun firing a full-power subsonic centerfire pistol cartridge. How would the CAT SC silencer perform on your self-defense handgun, in both long and short configurations?

SSS.6.118 - AAC Ti-RANT 9M-HD, 9M, 9 and the HK P30L

The AAC Ti-RANT 9M-HD is preceded in development, design, and distribution by two legacy models; the AAC Ti-RANT 9M (2017) and the original AAC Ti-RANT 9 (circa 2009). At the time of distribution, the original Ti-RANT 9 was colloquially referred to as the “quietest 9mm centerfire pistol silencer” available. The publication of this case study in the Silencer Sound Standard research pedigree, by PEW Science, is intended to recognize the historical significance of the Ti-RANT 9 family of silencers and to provide a state-of-the-art performance evaluation of the models on a modern host firearm.

In this review, all AAC Ti-RANT 9 variant performance metrics depend upon suppressing a full-size handgun firing a full-power subsonic centerfire pistol cartridge. How would any AAC Ti-RANT 9 silencer perform on your self-defense handgun?

SSS.6.96 - HUXWRX CA$H 9K and the HK P30L

The HUXWRX CA$H 9K is a compact 9mm pistol silencer that exhibits extremely low backpressure. At 8.0 ounces and 5.9 inches long, the CASH 9K is lighter and smaller than many other 9mm pistol silencers on the current market, while also exhibiting superior sound signature suppression to the shooter, using a full-size semiautomatic handgun. The holistic design and performance of the CA$H 9K is notable, especially for its size.

In this review, the HUXWRX CA$H 9K performance metrics depend upon suppressing a full-size handgun firing a full-power subsonic centerfire pistol cartridge. How would the CASH 9K perform on your self-defense handgun?

SSS.6.9 - Research Supplement: MOD9 FS, Obsidian 45, and Trident-9 Further Analysis

The previous Sound Signature Reviews of the CGS MOD9 FS (6.6), Rugged Obsidian 45 (6.7), and SWR Trident-9 (6.8) presented typical sound signatures of the silencers on a full-size 9mm semiautomatic combat handgun.

This members-only research supplement is intended to provide more information to PEW Science members with regard to specific sound signature characteristics of the tested configurations in the aforementioned reviews and to help frame objective loudness comparisons between the three silencers; both in first round pop (FRP) and average sound signature. This supplement is part of ongoing PEW Science small arm weapon system sound signature research.
