Carrying a Beretta 90-two in single action

[bellavite1]

Ok, this is gonna go down well...
So, here's the deal: I like my Beretta, I really do, but, given the same amount of practice,dry firing etc, I doubt that I will ever shoot it as well in DA as I do in SA.
No reason why I should either, SA is a shorter lighter pull, so, all other things being equal...
And yes, my finger discipline is quite good (last famous words...).
Anyways, this is not a training discussion, but rather a technical one:
It seems to me that , even in single action, a Beretta would be at least just as safe as your average Glock: trigger weight is similar, take up is actually longer on my Beretta and both have a firing pin block that will prevent them from firing unless the actual trigger is pulled.
Am I missing something?
