REDACTED Culture Cast 016: Alex Aubrey of Flux Defense and Tumi Tactics
Alex Aubrey discusses the SIG P320's modular design, highlighting the Fire Control Unit (FCU) as the serialized component that can be transferred between different grip modules and chassis. This system allows for significant customization and adaptability, a feature also seen in other handguns like the Beretta APX and IWI Masada. The ability to swap FCUs is a key aspect of the P320's appeal and its role in modern handgun design.
