I would describe mine as being the same. I only have one mark V. I have handled many others and don't recall flipping the safety on/off on others.
1st is a guess, it has a camming action, it's rotating one direction for on and another for off. So to put it on safe it very well could be more pressure needed to compress the spring or block a part to hold it, then releasing the same part. I don't see mine as a problem.
Advice, if you don't know how to take it apart. Learn how before hand. Make sure you have the tools needed.
Question: For as long as you have owned the rifle, has this always been doing this or is it new that this is happening. That would tell me if this is a problem or normal.
The last thing I would ever be worried about is a gun manufacturer replacing a broken/worn/nonfunctioning part. I doubt that any of those 3 things apply to this case. Just saying let them fix it if it needs fixed.
