Episode 318 - Rugged Obsidian 45 1911 .45ACP Silencer Testing and is the Silencer Form 4 going away? (20-AUG-2026)

Today’s Topics:

  1. Sound Signature Review 6.234 – Rugged Obsidian 45 in both long and short configurations on the .45ACP 1911 full size combat handgun. We first evaluated the Obsidian 45 on 9mm pistol back in 2020 in Report 6.7. Now it’s back – can it compete with the legacy AAC Ti-RANT 45? How does it compare with the KAC and B&T silencers? Does back pressure still matter? All of these questions are answered in today’s report. This is an introductory discussion. (00:09:39)

  2. Do you still need a Form 4 for personal silencer transfer? Or just a 4473? Great question. Let’s talk about this historic situation we haven’t had to think much about since 1934. (00:43:51)

Episode 310 - 6.5 PRC Silencer Testing: FOR Systems Predator 6.5 and AAC Ti-RANT 45 Tech (17-JUN-2026)

Today’s Topics:

  1. Sound Signature Review 6.227 – the original, legacy AAC Ti-RANT 45 on the .45ACP 1911 full size combat handgun. Standardized .45ACP pistol silencer testing is finally here! The performance of this historic silencer was examined in great detail in last week’s report. This is the technical discussion of the silencer’s performance. (00:09:15)

    a. Intro and recap (00:11:36)

    b. Ti-RANT 45 overview (00:14:35)

    c. Ti-RANT 45 silencer design (00:32:43)

    d. Hazard Map Brief 8.1.24 (00:43:30)

    e. System performance (00:49:12)

    f. Overall thoughts (01:03:39)

  2. Sound Signature Review 6.228 – FOR Systems Predator 6.5 with 6.5 PRC. Hunters rejoice. We’re adding combustion energy to the Silencer Sound Standard, gradually! And we’re killing two birds with one stone – shrinking jet diameter. Please welcome 6.5 PRC to the research pedigree. The FOR Systems Predator 6.5 kicks things off. Don’t worry, long action magnum is still coming later. Let’s talk about the method to the madness and just how much 6.5 PRC differs from .308 in today’s introductory discussion. (01:06:08)

Episode 309 - AAC Ti-RANT 45 1911 .45 ACP Silencer Testing (10-JUN-2026)

Today’s Topic:

  1. Sound Signature Review 6.227 – the original, legacy AAC Ti-RANT 45 on the .45ACP 1911 full size combat handgun. Standardized .45ACP pistol silencer testing is finally here! In today’s report, you’ll see one of the highest performing .45ACP silencers in history. Originally debuted in 2010, we’re about 16 years late, but making up for lost time. How does it stack up in the current day? Stay tuned as PEW Science shows you just how good you had it back then. Let’s push the industry forward, one test at a time. Also, why the 1911? We’ll talk about that too. (00:09:13)

    a. Suppressing .45ACP? Is it loud? I thought it was subsonic? (00:18:05)

    b. But why male models? (Zoolander joke). Why the 1911? (00:27:59)

    c. AAC Ti-RANT 45? Do they even make that anymore? (they don’t) (00:40:44)

    d. The current state of the pistol silencer market, and why it matters more than you think. (00:58:11)
