Bersa Thunder 380 plus

Wait a minute... are you saying that the firing pin hits the primer after you rack the slide?

You may want to pull the slide off and visually inspect the firng pin for any possible binding in the firing pin hole. Hole may be a bit tight or the firiring pin may be slightly bent or off center. Checking for debris or damage to the firing pin would be kinda hard cause you would have to remove it. The firng pin should be completely retracted into the slide when the slide closes on a fresh round. If is is proruding for any reason, there is something wrong and could lead to an AD.

You maybe able to manually work the pin with a push from the rear while the slide is off and the safety is in the fire position. You should be able to tell if there is any binding from misalignment or "drag" on the pin from crud or bebris.

Is it sill under warranty?

I took it apart and gave it a thurl cleaning. Went to the range yesterday to try it out. it seems to help, never had a discharge and no round had any Indentation.

That's good.
