The 38 Special/ 357 revolver dry fire cap is used to convert your 9mm (9x19) SureStrike™ to a 38 Special/ 357 caliber cartridge. The 38 Special/ 357 cap will reload your SureStrike™ with another minimum of 5,000 shots.
* You do not need to use a safety pipe and nut (safety system) when using the 38 Special/ 357 back cap.
** This back cap only works with the SureStrike™ 9mm (9x19) cartridge and NOT the Makarov 9mm (9x18) or Italian 9mm (9x21) cartridges
