My point is that the only time I would pull my gun is when I have decided that pulling the trigger is the only way to stop the threat....and I practice to make my draw to shoot time low enough that the person confronting me has zero time to react i.e. back down because they see the gun because by the time anyone sees it it is too late.
You're limiting the legal usefulness of having a deadly weapon. Texas law is explicit about there being multiple ways to threaten and use deadly force and sets out criteria for each. In fact, displaying a weapon to create apprehension of use is explicitly called out as not even being the use of deadly force.
Plus, where I come from (admittedly I am unsure of the law here) but if you show a weapon in a threatening manner in a situation that did not require it you are brandishing and have then broken the law i.e. if I pull my gun using it as a "you better stop because I have a gun" then I have just broken the law and I am now in legal trouble. Whereas if I pull the gun and use it because my llife was threatened then I am justified to have shown the weapon
This is TEXAS gun talk and we weren't discussing situations that didn't require deadly force. If deadly force isn't legal in a situation in Texas you're likely either committing Aggravated Assault or Deadly Conduct.
Please read up on Chapter 9 of the Penal Code to see the broader options for legal use of a deadly weapon in Texas when presented with legal justification.
