I have not read through all of these posts, so forgive me if this has all been resolved.
My advice to you is what I give to those who are scared to carry a 1911 condition one.
Stainless, for two days, carry your gun with the striker cocked, with a full mag inserted. At the end of each day check to see if anything happened while the gun was holstered that caused the trigger to be pulled.
You will see that while the gun is holstered, it is perfectly safe. Hopefully that will ease your fears.
(And when I tell people to try this with a 1911, I tell them to carry with an empty chamber, hammer back, with the manual safety disengaged)
Now, if I am going to be rolling around and playing with a child, then I do not want a gun that has a loaded chamber on me, either.
