Common problem of the PP750 is broken poppet valve causing air leaking out from the barrel. The material of the original valve is weak and combined with the super strong factory hammer spring the plastic part often shatters, which happened to me.

I have a few spare valves for sale. They are individually machined from Delrin rod and are drop in replacement for the original valve. They will fit on the factory stem as pictured.

Even though the Delrin valve is much tougher than factory valve, you still need to avoid firing the pistol when the pressure is too low. Without air pressure to absorb the hammer's energy the valve spring will bottom out and the valve might break again.

$16 each, shipped.
