Feinwerkbau 80 is recoiling

[Kennyb]

I have an FWB80 which was serviced about 5 years ago. I've not shot it for about 3 years and when trying it today the recoilless sledge mechanism doesn't appear to be working and the pistol is recoiling. When working correctly the sledge should recoil/move fully to the rear then if you tilt the pistol downward the sledge should slide forward and lock. This doesn't happen, there is no movement of the sledge at all. Even when it was working it did occasionally stick but it's not working at all now.

Could it just be lack of use? Any suggestions?

Is it lubricated?

[Ryde]

Clean and lube sparingly and it will be good to go.

I use FWB Special Gleitfett because that's what's in the case, but most any light oil will do

[Ryde]

If it still sticks after cleaning, then you need to check that the recoil rails haven't become misaligned

I could be way off but do these pistols not have a locking mechanism to stop the sled?

If it is not moving at all could this be the case?

[Kennyb]

Thanks for all the replies. I've been away so sorry for the slow response.

Regarding the locking mechanism, that's only on the FWB65.

Regarding lubrication, do I need to take it apart at all or can it all be done externally? I do have the FWB lubricant so can use that.
