I suggest that the best way to carry is the manner in which you feel comfortable and in which you will practice. The most important point is that you do carry. For myself, I am a bad guesser. That is one of the main reasons that I do carry. I can't guess when the violent threat will present, so I carry all of the time. Likewise, I cannot guess that, when the violent threat presents, I will have the use of both hands. I may not be physically able to charge my pistol. I want my pistol to ready to engage the threat the instant I deploy it.
Thus, I carry my DA/SA pistol with a round in the chamber and the safety off. My pistol lives in its holster, only coming out for use or cleaning.
FedEx says they will deliver my new everyday carry pistol today. S&W M&P M2.0, 9mm, 5 inch, in flat dark earth. I will carry it with a round in the chamber and the safety off. I am a bad guesser.
As with most things in life, how and what we carry comes down to which risks we are willing to manage and which benefits matter most.
