High Quality Content by WIKIPEDIA articles! The Walther SSP is a precision target shooting pistol made in Germany by Walther Sportwaffen. The SSP was created in response to ISSF rule changes to the 25 m Rapid Fire Pistol in 2005 which effectively rendered the Walther OSP obsolete. The new rules precluded use of the .22 Short cartridge as well as wrap-around grips and light trigger pulls (pressure required to pull/activate trigger).
