Cva express trigger issues

[slug1977]

I have a cva express.50 cal double barrel .went to show it tonight and the right hammer functions correctly but the left hammer will not stay back.took the trigger out , put it back in and functioned fine for 3 pulls of the Hamer and then won't stay back. Anybody have any experience with one ?

Take off the lock plate on the side that is affected and check for screws that have loosened off.

Any chance you over- tightened the cross bolt that holds the two lock plates in the stock? By doing so you can flex the lock plate and upset the sear/tumbler geometry.

^this, it's easily done.

I'll check that . When I took the triggers out the sear pins are not at the same (mirror image) from each others .is this normal?

Can you post photos showing the insides of the locks laid side by side? One photo with the hammers at full ####, another at half #### and a third showing the hammers down. Usually the corresponding parts are mirror images of each other.
