What is valve lock?
My SS shoots fine until I fill to 2100 psi. After that it doesn’t seem to be striking the top hat hard enough to release any air. It’s 177 w/12″ barrel.

Hi,
I think he should try adjusting the tophat. The hammer in the talon is heavy enough to get to 3000psi.
Unless something was changed (spring or hammer) the solution is to adjust the reach of the tophat.
If the tophat is too far back, at higher pressure the hammer will barely impact it and won’t be able to move it.
Also it could be that the stem is gunked and needs to be removed and cleaned. Maybe a little silicon grease on it.
My 2c.
Cheers
Chris
