Diana Bandit .22 PCP fires with safety on.

I haven't shot this pistol in a long time but today I got it out for future pest control.  Since I was planning on having it ready to go, I checked the safety.  It fires when the safety is on or off.  I thought, maybe trigger engagement.  Backing that off didn't help.  It looks like the safety relies on hitting the trigger guard to inhibit firing.  I'd have it a part but my 3mm hex key is missing in action.

Has anyone had this issue?  If so what did you do to correct it?

Thanks!

Found a 3mm key and looked inside.  I ended up cutting a shim that fits in the back of the trigger guard and presses against the trigger housing which reduces how much the trigger can swing before the safety hits the trigger guard.  That having worked, I added a second shim to make sure.

 I see you got it sorted, IIR I had a similar issue when I modded one of my SPA airguns.
