What causes the pump slide to automatically slide completely to the rear position when being fired? I've tried different loads and no difference, I've taken it apart and cleaned and re-assembled, still no change. A friend said he has one that does the same, what can be done to fix this?

your hand not being on the forend.

when you pull the trigger it keeps the action unlocked.

to lock the action you need to cycle the gun again without pulling the trigger.

My 500 does the same and I'd wager every other pump gun will too as 12ga generates a good bit of reward energy.

it's perfectly normal

Why would you not want to immediately cycle a new round and eject the empty when you fire it?

exactly. It'd be pretty damn inconvenient for a fast follow up shot to hit the action release again.
