C'mon...Anybody??? 870 Bolt is "loose" after trigger is pulled. Video added.

Hi,
Am I missing it? Is this normal?
My 50 + year old 870 is doing something "weird" I think.
Unloaded (or loaded) after cocking the action the bolt is locked forward, as it should be.
After squeezing the trigger the bolt moves easily a 1/4" back (towards the rear).
So does the fore end (the part you rack back to cock the gun).
It seems to me that some part should be holding the bolt, etc. locked forward until the gun is cocked and readied for the next shot.
Could it be that the "Action bar lock" is shot?

Attached is a very short video showing what is happening.
The empty gun is held straight up and down.
Cocked, the bolt is locked.
Trigger is pulled and you can see the bolt fall back maybe 3/4 of an inch.

Is this normal??? (I don't think so.....)

Yes, that's normal for a well-used 870. The 870's action bar lock disengages right as the hammer falls, unlocking the slide. This does not unlock the bolt, but it allows the fore-end to move rear-ward, which does unlock the bolt after a small amount of initial rear-ward slide travel. When you hold the gun vertically and pull the trigger, the slide falls down under its own weight, unlocking and slightly retracting the bolt until the uncocked hammer stops it.

Yes, it is absolutely normal.
