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)
