Who this model suits

Choose the P-25 when a compact pellet-only CO2 pistol, rifled barrel and blowback slide are priorities. Blowback uses part of the CO2 charge to cycle the slide, so shoppers comparing shot economy should also consider a non-blowback model.

Operation and compatibility

• Use compatible 4.5 mm pellets; this is not a steel-BB magazine format.
• Use the 12 g CO2 cartridge type specified in the manual.
• Check pellet length and magazine fit before loading, then follow the manual safety procedure.
