That's why you use procedures that ensure that if a mistake is made, there can be no serious effects. Hence, why I said, " ...0% chance of discharge unless you have problems with your thumbs becoming insubstantial." If you screw up, you just have a hammer on your thumb. If you do have thumbs that are prone to becoming insubstantial, then you have problems larger than choosing DA/SA or Striker.
And yes, in general, if a procedure has been in use for thousands of repetitions with zero failures, it is considered safe.
And no, your opinion shouldn't catch much heat. It's clearly stated as an opinion then not backed up by anything what so ever, so it can just be discarded and ignored. You might as well have just said, "Elephants aren't very good animals. Rhinos as a little better, but not much."
Although, you did open the door to an all new hilarious path to take this thread. If you think DAO Striker is inherently safer than DA/SA, let's talk Glock Leg. A particular issue so common with striker fired guns that it's been given it's own name. Funny now that I think about it how Beretta, 3rd Gen Smiths, CZs and the whole herd of DA/SA guns managed to avoid having a term coined for how their users manage to accidentally shoot themselves..
And no, 1911s are not DA/SA, so they don't really belong in the discussion.
