Well, those are also opinion pieces, just like this thread, with only 2 examples of someone who had his gun taken.
Not exactly a landslide of factual stuff.
If people were being shot daily because of open carry (we are not including gang to gang related stuff) I might think to only cc.
Until then, I will continue to carry either way, dependent on what I'm wearing/doing.
Your argument does not really stand up to a lot of scrutiny, it seems more of a personal choice possibly mixed with a little paranoia.
And yes, for me it is easier to open carry, because I'm not a slim person.
Either way is doable, but it is what it is.
