There are a number of firearms designs that will not operate smoothly and correctly, UNLESS they are operated "smartly". This includes many manually operated repeaters as well,. There are pump, lever and even bolt actions that do not operate smoothly, or even jam, unless the action is worked at the right "speed".
semis are built to close under their own spring tension. Anytime you "ride the slide" or "ease the bolt home" you are taking a risk, and it is no fault of the gun, or its design.
The one allowable exception, and in my opinion usually a good idea, is to ease the gun shut when closing the action on the EMPTY gun. It hurts nothing, and might possibly extend the life of some parts.
If you are easing the gun shut while chambering a round, because there is human or game animal close enough to hear the noise of normal operation, and you don't want them to hear it, you are loading the chamber in the wrong location.
There is always a "safe" place to load the weapon, BEFORE going into action, where the sound of it loading normally doesn't matter.
Always.
Your new S&W should be fine (once broken in), might be fine right out of the box. Having any issue when you interfere with the gun's normal cycle is a not a flaw of the gun.
