There is a thread below about repairing a broken decocker in a CS-9, I think - that was the first time I ever heard of that happening although I should not be all that surprised because anything mechanical can break.

Query - is there a way to "notice" that your decocker is not working correctly?

Query - if the decocker fails can you expect an AD?

If this has been discussed before please point me in the right direction.

Comments definitely solicited.

The decocker in that CS9 wasn't actually broken... There is a chain of part that must operate together in order for the decock function to safely lower the hammer from full cock. You have the decocker body which acts against the sear release lever which in turn acts against the top of the sear to press the sear forward out of engagement with the hammer's full cock notch.
The sear release lever is the primary 'wear item' in this chain so, when a sear release lever is I'll fit or just plain worn out the weapon will fail to decock

Not my intent to sound sarcastic...
The answer is yes...when your hammer is at full cock, you lower the manual safety lever or decocker to the safe position and nothing happens....The hammer remains at full cock.

Briefly...you cannot decock the weapon by actuating the manual safety/decock lever.

In such a case the only way to lower the hammer is by pulling the trigger


Nope, your just unable to decock the hammer without pulling the trigger.

You just have to stay on top of your safe manual of arms practices. There is a greater risk of an ND in this case since clearing and making the weapon safe becomes more complex. Assuming the magazine disconnect safety has not been disabled/removed, you'd have to deload the arm... Then with an empty magazine inserted close the breech and pull the trigger to lower the hammer. Greater risk of an ND there in my opinion.

Your firing pin inertia block safety is still there so the only way the gun can go Bang! is someone pulled the trigger.

Cheers
Bill

Thanks to an old post by a very knowledgeable friend, I bought a box of eraser-tipped wood pencils. Dropping the pencil, eraser end first, into the barrel makes it very easy to verify the fundamental function of a decocker and hammer. If you decock the pistol and the pencil moves, that's not good.

Jeppo, I like it.

But, Bill, I didn't take it as sarcasm - and you answered my question precisely! Since I never had a decocker fail it never occurred to me that the failure would be failure to decock, that the hammer would literally not drop - that's a way better result than a failure where the hammer does drop and you blow a hole in your floor/wall/bed/whatever safe direction you pointed the gun.

Thank you!
