Some prefer to keep a round chambered which in pump/autos means hammer is cocked. Not a good idea as springs are stressed to their max and left for long periods MANY will take a "set" which means when you pull the trigger after a few months/years storage you may will hear a faint click rather than have your ears ringing a bit.

We had a spring engineer at Picatinny Arsenal when I was there and I specifically asked him about spring compression in long term applications. His response was classic which was along these lines:
"A properly made spring should never take a set."
"Unless you have the means to determine if it has taken a set the only way to determine it has is leave it compressed for a couple years and disassemble the weapon and measure the free length of the spring."
At Aberdeen we disassembled every weapon coming in for test. In the case of compression springs we measured the free length of spring at zero and every 1200 rounds.
In the case of rotational springs (870, ARs etc) the springs are removed and photographed in such a way that if the ends of the springs move we knew how much they moved and confirmed they had attained a different position i.e. lost energy potential.
Just remembered a ground shaking event. We got in a new handgun design come in to evaluate and the procedure at FLETC was to store autos with
slides to the rear and muzzle slid over on aluminum pin on a rack and placed the the security area when not in use. Each rack held 10 guns and you could tell in an instant how many were in a certain section.
We had shot them like 500 rounds on a Friday, they were cleaned and stored as indicated above and on Monday morning I pulled them out to continue testing.
NOT ONE OF THEM HAD ENOUGH ENERGY TO STRIP A ROUND FROM THE MAGAZINE AND LOCK THE SLIDE IN BATTERY! ! !
I realized immediately what had occurred and called the factory rep within minutes and warned him in the strongest terms that he had better call their engineering folks quick and get them on this as this was going to be a marketing disaster for the firm if the slide spring problem was not corrected quickly. I have not been aware of that happening with that design since.
The moral of what springs can't do for you can get you killed.
I think it was Bill Jordan (USBP Ret) and author had a quote along the lines of," no one has ever been killed as the result of a loud noise" the intent being if you don't hit them they don't get impressed. I would add to that "No one has ever been killed as a result of a faint click noise."
As someone stated racking a pump gun may or may not intimidate anyone as firearms ignorance is rampant among the public these days and they may not know what caused the mechanical noise they just heard.
I have two 870s, both with 00 and both with empty chambers, hammers down. One in bedroom and one in living area.
Additionally I have seen FEDERAL SPECIAL AGENTS pick up a revolver/automatic from a box full and pull the triggers without clearing it multiple times. Forrest Gump's mother had a saying for such.
I picked up a 9MM auto from a box full (just piled in like corn) and racked the slide to check it and a loaded round popped out. Two guys were there checking them in and they saw the loaded round pop out on the floor and it shook them for sure. The magazine was empty.
