Joshua Waldron, CEO of SilencerCo, posted this image on Instagram. The image on top is a early prototype of the Maxim9 integrally suppressed pistol. The early versions were built off of S&W M&P9 but this looks like it was built on a Beretta 92. What I find the most intriguing is the transparent window allowing us to see the baffle design. Very cool looking. It reminds me of a Nautilus shell cutaway.
