OK - we caved. For as long as we've been doing this series we've given our followers the chance to guess the weapon on social media before our video goes live. Without fail, there is always at least one person who guesses it's a hyper realistic cake (you know who you are). So, in what will be her last episode with us, WitW Team Member Emily kindly baked us up an SR-1M in an attempt to appease the the cakers out there.

Join Jonathan as he slices into the history of this hard-hitting Russian pistol used by security and secret services alike.
