Gee whiz, if all break open shotguns were built like Ljutics, we would only have the dry vs lubed side of the discussion. What sort of confusion would there be with only a push button to open it. Try pulling on the button when closing a Ljutic.
Having owned houses and trucks for many years, I can say that if you have to start slamming doors, it's time for at least some maintenance, possibly adjusting. As has been said previously, shotguns, like house and equipment doors are designed to be closed with a firm action, not a slam.
To get way off topic, my first owned residence was a 1959, American made, 8' wide, mobile home. The front door was formed tin. It had been slammed too many times. The result was that when the latch bolt locked, the centre part of the door stayed closed. The top and bottom, however, bounced off the foam rubber weather strip, bending the metal, and caused the door to be bowed outward top and bottom. This was great in the winter! It got fixed with a length of angle iron bolted top to bottom. Of course this was back when I had better things to do, like go out and shoot my then completely, off the radar, FN FAL. That was a few years ago.
For those still following my ramblings, time does not change certain basic rules about treating equipment, machinery, or any other mechanical device. Abuse it and you will be rewarded with a failure. As for closing break open guns, mine are always lubed, and I close them carefully, but firmly.
