Revolvers are designed for adequate strength and minimal weight when produced as designed. When the chambers are drilled where there is less than the designed amount of material around them, there is no way for an end user to know if that is safe and every reason to suspect it is not.
There's only one way to tell for sure, and I'm not anywhere near curious enough to pull the trigger on that setup myself.
S&W should be mortified that this gun got manufactured in the first place, and then through all the QA checks and out of the factory.
With a flaw that obvious, it begs the question of whether or not there are any QA checks in the process.
