First: Great Response, Fitebak. Glad you got some good info and had a good experience in your course! Feel free to let everyone know who you trained with!
D-man,
Thanks for checking out the DVDs. I'm not sure who was teaching out in LA, but I'm sure it was Viking Combatives. Some of their instructors are the guys that I fly around the country when I need to augment the I.C.E. staff. They are top notch.
Let me say that I LOVE this statement:
In fact, going to a square range and not being able to move feels unnatural now.
It is something that most of our students start noticing pretty quickly. Standing still while drawing or reloading without a nice piece of cover just doesn't make sense...
What FB posted is a pretty good summation of our thoughts on the WEaver issue. While I have had students get through a 2 day course and still be fighting (perceivedly or not) going to weaver, we find that most people break that habit pretty quick. Part of breaking the habit is understanding intellectually why it is probably inconsistent with your body's natural reactions under extreme stress/surprise. In the absence of training, people will lower their center of gravity in response to being threatened or surprised. This is a natural instinct and it prepares us to move. This lowering of the center of gravity (bending at the knees, specifically) is necessary to move into a bladed position... so, what many people consider "automatic", is actually a learned SECOND STEP after a stimulus response. For this reason we identify it as inefficient.
As noted by FB, it is certainly possible that you will be attacked in a circumstance where you DO NOT blade (seated, for example) and we want your training to be as consistent as possible with a worst case scenario, not a best case.
Lastly (for now, at least!), while the isometric tension created by pulling back on the gun with the weak hand DOES increase deviation control, it does so at a rather huge cost in terms of bio-mechanical simplicity and consistency between 1 handed and 2 handed shooting. We know empirically that MANY defensive shootings are conducted 1 handed instead of 2, even when the second hand is available. One of my theories is that the brain intuitively recognizes that most people take a relatively long time to create the weaver grip, and that process is skipped in response to an actual threat. Regardless of the validity of that theory, training to get a quick and convenient support hand onto the gun while the gun is in motion from the holster to the threat with a strong hand position and body position that is consistent for either 1 or 2 handed shooting seems to be easy for people to learn and execute efficiently under stress.
Keep in mind that we sometimes have to suffer through un-training bad habits before we can become "comfortable" with new, more efficient, techniques.
Thanks for the question!
