Landing gear problem (was "oh! crap")

[SkyKing]

I guess you made it back to the ground in one piece? Sounds to me like the gear pack isn't toggling back. On the ground does it make a quick Zzzziip sound when you hit the master as it repressurizes? What I usually do on the ground is pull the CK breaker for the gear with the master off, pump the gear doors down with the floor handle for a look-see... then with the CK breaker still out, throw the master to the on position... which toggles the valve... then pump the gear doors back up to their closed position. What year is your P? Didn't some of the earlier models, like '73 through '75, come from Wichita without the extra pressurizing gizmo over the mains? Seems they added that later on, but I might be wrong... anyway... if yours has that particular item, maybe it's lost its charge???
