It is. I've heard that before on not carrying on half cocked but never understood why. To be honest, I didn't want to look stupid for asking. Now......after years, I've looked stupid so many times, my skin has thickened...Ha.Because it was not designed to be carried that way is the best I can come up with. Hi Powers and 1911s can be carried the same way, but, again, were not designed to be so carried. And I believe the half cock position is the "one position" you mentioned in the above post.
You can put the safety on in the half cocked position that just stops the trigger from pulling. Fully uncocked, the safety will not engage.
Learning curve question on something I've heard before. I'm sure the answer is simple and I'm a simple man.
