We have been using the Dry Fire Mag for some time now. It is available for many different gun manufacturers. We use it in the Sig Sauer p320 and the p365. It gives you a constant reset trigger without having to rack the slide each time.   It is available as a stand alone dry fire magazine or they also offer a SureStrike Mag that can be used with a special laser cartridge that enables it to be use with laser training products such as MantisX, Laser Ammo or Strikman systems.
