Pointless. snapcaps are more useful - A-Zoom StrikerCaps

Product works as intended, didn’t think this purchase through enough before hand. Using a semi auto, mag fed, striker fired handgun. For the stated purpose these do exactly what they claim: remain in place while dry firing, however for my use case the same training can be accomplished on an empty chamber. Prefer Snapcaps as they have more utility (I.e testing functionality of gun/mag, training etc) although their downside is you need to collect the em after cycling
