It sounds like the reg is leaking through, so the hammer is seeing twice the pressure it's supposed to. Take the reg apart and replace the seals yourself, or accept that you'll be selling the gun for a fair bit below to allow for the cost of the repair.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
