Slide Release

A majority of people have a problem reaching the factory mag release of the Ruger 57 as it is too small and needs the shooter to rotate the pistol in their hand to reach it. F5 has brought the extended magazine release of the Ruger 57 to adjust to customer aesthetics and functional needs. The steel-made extended mag release is easy to install and delivers ease of usability. 

The slide release in a Ruger 57 is too small and complicated for new users to operate. The extended slide release from F5 works better and faster on the Ruger 57. It makes pulling the slide easier and facilitates faster reloading of the new magazine.
