These are both salient points. The reflexive dynamics of stance/draw/fire action is important as a base model
. Violence can erupt suddenly in an environment not of your choosing. Terrain, obstacles, bystanders, time-of-day, visibility and lighting, weather, how you are dressed, your state of health, the level of competence of your opponant, the adrenal effect and a host of unknown quantities can factor in.
An example: In the opening seconds of a night firefight in Vietnam--a react-to-ambush--one of my VN NCO's had his glasses knocked off as he dove for cover. He spent a few precious seconds retrieving them--because retrieving precious dropped eyewear was his instinctive first reaction--and it taught him a lesson about the necessity of wearing a neck strap and of priorities.
So you have to expect that unexpected things will happen. As a rule, I think it's important that you practice from a variety
of positions, under as many different conditions as possible. Shooting from the left and right or over and through a barricade is good training, shooting from a crouch or from your knees, shooting effectively one-handed from both strong and support side. But this in no way should diminish the importance of achieving the instinctive reflexive base stance and the smooth kinetics of draw and fire. Reach that natural reactive stage and the rest will fall into place with repetition. Just my 2c.
