The Walther OSP is manufactured by Walther, it is a pistol chambered in the .22 Short caliber. The OSP was designed for the Olympic 25 m Rapid Fire Pistol event and became the perennial winner of the event. The pistol features a Morini grip, which places the bore at a lower level to reduce recoil. The barrel is weighted and ported, and felt recoil is virtually none. It comes with either a 2.2 lb (1,000 g) or 3 lb (1,400 g) trigger.
