Default Re: Luger Carbine (Erfurt) No Stock

Ron,

The 1902 Carbine needed the return spring in the forearm due to the flat mainspring not having enough tension to return the barrel to battery reliably. The 1920 carbine had the coil mainspring, and the return spring was no longer needed due to the extra strength of the coil spring.
