OK, I'll take the points about finger placement--
but it seems to me that you are arguing for a use in which the parameters are fairly complex, and really beyond the appropriate civilian use. I agree that having one's finger on the trigger on a SA auto makes it an issue; here, I'm defining that issue as one of an AD/ND (and let's not, at least for the moment, segue off into that semantics discussion) caused by adrenalin / motor skill issues--the proverbial unintended discharge.
IMO, the civilian use is based on having identified an immediate deadly threat, drawing, and at least preparing to shoot by having one's finger on the trigger. One simply doesn't present the firearm unless the threat is deadly. To do so brings up the "brandishing" and "escalation" discussions--which are, I think, antigunner feints in politics, but equally-significant factors in the legal issues for carry-ers. Perhaps, then, this discussion is not merely about the apparent conflict between sacrosanct gun safety rules and the use of a certain-brand laser, but also about the legal constraints of civilian use and carry.
So, then perhaps those of us who carry should select only DAO handguns? 1911 guys should carry only the ParaOrd long trigger type? Personally, I resolved this 'intention' / safety issue by selecting DAO handguns. My first carry gun some eighteen years ago was an SP101 with a bobbed hammer; the second was a Glock 19 (with a laser), and the bedside / holster-type was a S&W 4046 (or something like that). A third semiauto was a CZ-75 type, an EAA Witness 'Carry Comp'--which allowed a DA trigger stroke for the first shot. At that same time, I was fairly proficient with 1911s for shooting in club-level 'action-type' competition. But, I didn't want to routinely carry a 1911.
The solution is probably new / different devices--e.g., different laser placement. The new S&W revolver, its response to a Ruger LCR, has this in a laser mount up at the top-rear of the frame....
