To blame those 40,000 deaths on firearms is a bit asinine, don't you think? 61% of those deaths are actually suicides. So why don't we collectively approach this figure in a systematic way? If more people are committing suicide, what is going wrong with our mental health care? Blaming guns for this is such a cop-out and we will never be able to get to the root of the issue. If someone wanted to commit suicide, they'll just turn the ignition of their car on in an enclosed garage.
And no, I'm not accepting of any deaths at all. But as a society, we must understand that everything comes with a cost.
There is substantial evidence that a lot of people won’t choose to commit suicide another way if blocked from their preferred route. Method does matter in of itself (the guy who wanted to jump offf the Golden Gate bridge but didn’t want to get run over for instance

Even if there is 100% substitution of intent that still would not equate to 100% success, as you yourself pointed out guns are a very easy and efficient method of taking a life.

The effectiveness of restricting access to certain means of committing suicide has been demonstrated, at least as regards toxic domestic gas, firearms, drugs and bridges. At the individual level, studies tend to indicate that many persons have a preference for a given means, which would limit the possibility of substitution or displacement towards another method. Similarly, the fact that suicidal crisis are very often short-lived (and, what is more, influenced by ambivalence or impulsiveness) suggests that an individual with restricted access to a given means would not put off his plans to later or turn to alternative methods. This has been more difficult to demonstrate scientifically in population studies. Nevertheless, it appears that, should such a shift occur towards other means, it would be put into effect only in part and over a longer term.
