Thanks gents for the speedy responses.

The 870 is 2 months old and fired 300 shells max.
Push pin is neither mushroomed on shell end or on hammer end ( although there are strike marks).

The light striking ( cant think of a better term )
If the shell doesnt go off when struck if i reload it into the tube re rack the same shell the second strike sets it off.

The gun has done it from new so i dont believe it is caused by wear. I have 38 shells and it isnt the same shells it appears to be random. And none of the shells are that worn.

I fully stripped the mech and checked full trigger assembly and can't find any excessive wear.

I have removed the pushrod sheild to see if it was added friction ect and repoved the vast amount of grease it was shipped with.

Bit stumped if im honest.

Thanks
