I dont know if the snap caps do anything to prevent this or not, but I figure they cant hurt.
I dry fire my one 17 pretty heavily, and pretty much daily, and have done so for the past 8 years or so. I do use snap caps (AZoom's), and this is one of the reasons why. The other is safety. You cant "accidentally" have a live round in the gun when the snap cap is in there. The AZooms last a good long time and are cheap enough.
I shoot this gun at least once a week, and considering its just passed 122000+ rounds this past weekend, and its easily got 10 times that in dryfire, and so far, the only thing to have broken has been a trigger return spring at around 90,000 rounds (the gun still actually functioned with it broken too), I figure I got my money out of it, and those AZooms still arent hurting anything.
