F5 MFG has recently announced their support for the Ruger 57 which is Ruger’s very-own 5.7x28mm chambered pistol with their new magazine extensions.

F5 MFG states “Machined from 6061 T6 Aluminum and Cerakoted Black, Grey, or FDE with a clear coat for additional wear strength, this extension brings the capacity of the Ruger 57 to 25+1 rounds of 5.7×28.

With a locking device machined from aluminum, secured in place, this magazine extension will not only provide you with additional capacity, but won’t fail under heavy use.”
