Pulling the trigger on a snap-cap should never be an issue with any gun as long as you don't do it in a rapid manner, even a striker fired one. Doing a dry fire with a snap-cap (which I recommend) is a little different with most striker fired pistols, you need to rack the slide to reset the trigger and the striker. This will of course eject that snap cap, so you would need multiple snap-caps loaded into your magazine in order to do it more than once at a crack. There are some ways to circumvent re-racking the slide, none and I mean none of these are good for your pistol and will damage it to the point that the trigger will no longer function.
Added Note: Pulling the trigger on any gun in a repeative and rapid manner will weaken and break at least one of the springs in the trigger group.
