Since 2016 The Sp-HO project uses an universal frame. The new frame is compatible with all newly manufactured models in both calibers .22 LR and .32 S&W. In caliber .22 LR: Rapid Fire, Sport and - in the USA - Bullseye; in Center Fire: .32 S&W and for the USA market .32 ACP caliber. This transforms the trio of international prizewinning pistols into one true, convertible weapon system. Conversion kits are available and the latest generation pistols can be used in all ISSF 25-meter target shooting disciplines. The new frame can be used for Rapid Fire Pistol, 25 m Women Pistol, Junior Sport Pistol, Standard Pistol, Center fire Pistol and Bullseye Pistol events. The advantages of the new SP-HP system are numerous: same grip, same trigger settings, interchangeability of the parts, versatility of the events that can be shot, compact carry size, lower cost. Some of the older generation barrels and bolts are also compatible and can be used on the new frame.
