Alright TDC - Since you asked so nicely, I'll play one more time. You asked about the use of cover and how it relates to using a holster safely. Here goes:
In order to achieve the highest probability of safety, when approaching low cover, with your firearm holstered, you should:
A - Draw the firearm BEFORE kneeling behind the cover
B - Kneel behind the cover and THEN draw your firearm
C - It doesn't matter, do whatever is fastest
Best practices in holster training says the answer is always A. Some would argue get behind that cover first cause the bad guy is shooting at you. However holster instructors will point out the fact that if a bad guy is shooting at you, you are in a high stress situation and bad things are far more likely to happen in high stress situations. You can forget things like ACTS and PROVE and this can have serious consequences.
ACTS and PROVE are completely retarded and anyone who subscribes to them hasn't the faintest clue about what they're doing. Its gov't bullsh*t designed by an incompetent clown. Where you get this idea that I support them or that they are valid is beyond me, but it speaks volumes as to your level of training.
If you had kneeled and then drawn, there is a high probability that at least one of your legs is forward of the gun and holster - this is simple body mechanics, one of your knees is forward of your waist. If you were to hit the trigger in that draw, you could easily shoot yourself in the leg. So the best practice is to reduce/eliminate that risk by teaching shooters to draw BEFORE they kneel and not the other way around.
If your response to stress is to slip your finger on the trigger, you need more training, hence the reason you train. It is not always practical or possible to draw then kneel, so teaching "the safest" method as the only method is ignorant. Outside the competitive arena that is the REAL WORLD, guns get pointed at all kinds of things and people. It is the discipline with your finger that counts the most. I've drawn from prone, supine, seated in a vehicle, seated at a desk, I've even drawn while rappelling. What has never crossed my mind regardless of where or what I was doing at the time, was placing my finger on the trigger. The fundamental four ensure you don't have an ND.
Now you are no doubt going to say that if you had just followed ACTS and PROVE it would accomplish the same thing so the training is unnecessary (I read your mind there, didn't I). And your holster instructor is going to agree with you and then point out that we just said this was a high stress situation and that you are human and capable of making a mistake and that only a total phukking idiot doesn't stack the deck in his favour when possible (I'll assume you agree with this). Adopting this best practice reduces risk and the probability that you will accidentally shoot yourself so why wouldn't you do it?
The instructors I've trained under all carry for a living and most have shot people, a lot of people. I agree that training can and does improve ones abilities. What I don't agree with and what you seem to gloss over is the reality that training is NOT REQUIRED to use the holster SAFELY, it is required to use the holster EFFICIENTLY, there is a big difference. I agree that as humans we are capable of making mistakes, would you agree that even with training you are capable of making a mistake??
Further to this, there is a second reason why we would draw BEFORE kneeling and that is efficiency. What if a shot presents itself before you are fully behind cover? Does it not make more sense to be prepared to return fire as soon as possible? To have the firearm comfortably welded to your hand as soon as possible? We have a second benefit to this best practice, beyond the realm of safety.
What is more important, winning the gunfight or not getting shot??? The situation dictates the tactics so a broad answer such as the one you present is neither true nor false. In your scenario you need to address a few more factors. How far away is my target, do I have the skills to make the hit on the move at this distance? Would seeking cover be more advantageous than taking a low percentage shot? Does my target possess a superior weapon like a rifle, is he sighted in? Too many variables to say that drawing prior to taking cover is the answer, but I'm sure you knew that.
Now, I'll warn you now, if you start debating this best practice, we are done. You don't get to ask me for a textbook answer (you are free to validate this with any holster instructor you know) and then say you disagree with the textbook, especially since you already admitted to not believing in holster training and you are a believer in ACTS and PROVE and this practice is simply an extension of that.
You need to work on your comprehension. I am by far one of if not the most vocal proponents of professional training. What I said was this: YOU DO NOT NEED TRAINING TO RUN A HOLSTER SAFELY. YOU DO NEED TRAINING TO RUN A HOLSTER EFFICIENTLY.
There's your example. Holster training is filled with these type of best practices that keep people from injuring themselves and others. And while some, most or even ALL of them may come down to extensions of ACTS and PROVE, using a holster introduces so many more things to think about, it only makes sense to focus on reducing risk and complexity. Of course, the training then advances to making these actions smooth and unconsciously competent.
The addition of a holster adds a lot to think about yes, but it doesn't have any bearing on the fundamental four. There is no difference between running a holster and not, when the gun is in your hand you follow the fundamental four. The gun doesn't know where it is or where it originated, it only does as the dumb meat stick behind it commands it to do. If adding a piece of leather/kydex alters your handling habits, you need to TRAIN more or stop using firearms. As I've said several times in this thread, training is always a good thing, but its not a necessity. Proper training with regards to efficiency will greatly improve the speed at which one can draw.
I will reiterate, ACTS AND PROVE ARE GARBAGE
Given your 150+ hours of training I would have thought this would be very obvious to you. Am I wrong?
I'm well versed in the use of holsters, cover, concealment, etc. Please enlighten us all as to your credentials? So far it sounds like you're a big fan of ignorant sh*t like ACTS and PROVE and feel that safe firearms handling is impossible without training. I have to ask, if training is required prior to safe handling, then how did we as humans get this far? Someone had to try the methods and techniques we now teach, so who taught them??
I'm in the bold, please read carefully...
