We had the stock sear that holds the piston break under 30 rounds, with the stock spring.

And you basically have to buy the whole kit (pain in the ass to install, as it requires drilling/tapping holes), or your piston won't lock properly with the sear, as the stock cylinder is not really compatible with this kit, It slam fires if you aren't careful in pulling the bolt back.
