acparmed, 10-4 your last. you brought up a great point ref. "blinding muzzle flash". The people that I teach the CCW(kinda) course to are somewhat new to the CCW type of carry. These people for the most part already have the CCW license. They are the wives of soldiers and sailors that are deployed overseas fighting the dirty little"wars" that our politicians have chosen to get us involved in.(Don't get me started !!!) I want them to be prepared as possible for what they might face out in the hard,cruel,world. That,in my opinion,includes more than just the BG's and how they act,move,and their motivation to decide who will be their "prey". A big part of my training is knowing your weapon of choice and what it will do(get accomplished) with proper training and knowing WHAT TO EXPECT. Part of the what to expect is several sessions of night firing. We shoot at an outdoor range so we usually start about sunset with the usual safety briefs. I break the class up into two parts so I can "Watch" all the students as it gets dark. IMHO everybody should go through these types of drills with the weapon of their choice. I have had students change ammo,change stance,change their grip of the weapon,even change weapons. Especially if they have chosen to carry a revo or a ported weapon. I do not teach that they should not make the choice to carry one of these,just that they should be aware of what to expect when they pull the trigger in a "no/low light environment. I have read reports that have stated what percentage of all shootings take place in a no/low light environment(I can't remember the exact figures)and it is a heck of allot more than most people believe it would be. Given this,I feel that you are doing your students an injustice,if you don't teach this along with the obvious stuff. Even the "pros" should include some night firing in their training. You might see some of them descretely changing ammo or weapons. This,of course,is just one humble opinion. Remember----YOU HAVE THE RIGHT TO DEFEND YOURSELF---
