2. Sound Signature Review 6.230 – Strategic Sciences MFMD + SDX on 20-in .308 bolt-action. One of the most interesting silencer systems we have evaluated in the research, to date. The multifunction muzzle device, like all silencers, suppresses recoil, flash, and blast. How does the MFMD compare with other things on the market? Are reflex designs making a comeback? Introductory discussion for this very high performance system. (00:58:17)

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)
