Sauer 38H won't stay cocked

[jcjohnson]

Any ideas on how to get a Sauer 38H .32 ACP to stay cocked when it cycles?
It is not short cycling, but the hammer doesn't reset every time.
Thanks in advance!

Here's an exploded view:

Things to check are a gooped-up action from old grease and fouling.
Check the springs fro presence and strength.
Check the hammer notches, the sear tip, etc for wear, chips, or alteration by "Billy Bob".
Make sure the de-cocker assembly is working properly and isn't forcing the hammer to de-cock. Check the springs and for a frozen de-cocker assembly.

Still won't stay cocked

Things to check are a gooped-up action from old grease and fouling.
Pistol is clean and properly lubed
Check the springs for presence and strength.
All springs present, seem fine in tension.
Check the hammer notches, the sear tip, etc for wear, chips, or alteration by "Billy Bob".
Hammer and sear fine, no evidence of alteration.
Make sure the de-cocker assembly is working properly and isn't forcing the
hammer to de-cock. Check the springs and for a frozen de-cocker assembly.
De-cocker insert in sear moves freely, de-cocker lever seems to work OK.
Trigger bar disconnecter works fine.
When cycling slow by hand resets every time, cycling rapidly fails to reset
about 30% of the time.
