WTB Pardini GPE or HPE or a dry fire timed/rapid fire training system

The title says it all.  I am looking to buy a Pardini GPE or HPE strictly for rapid/timed dry fire training.  I am open to buying a dry fire rapid/timed training system as well.  But, everything i have seen that works for rapid/timed adds an appreciable amount of weight to the pistol.  I have a training system that works just fine.  But, it needs a hammer fall to initiate the laser.  I believe an electronic hammer pulse will do the trick.  Thanks
