I’m pretty sure pull out a bigger gun is being used as a euphemism for having a gun under the table, or basically just having a better weapon then they do with an inherently faster draw time.
Indeed. The gun in this case is a metaphorical gun. The real object under discussion is a piece of information that was being used as blackmail against one of the characters, and the eventual response to it was a blend of calling their bluff (the blackmailer did not have the proof he claimed to have) and pulling out the bigger gun (a piece of information that was used to blackmail the blackmailer).
