This just proves that you need to know what your particular bubble is. Having a firearm on you to protect yourself is useless if you cannot deploy it properly in the reaction time you are given. When somebody is chest bumping you backward with their hands all over you definitely puts you at a disadvantage when drawing. I try to practice a last ditch draw method where I create space from a 0'distance "just in case"
I draw from the right side, so left handed persons are the opposite of course. This assumes a carry with an open top IWB/OWB holster at a 4 O'clock position.
1. First do your OADA (observe, assess, decide, act) to determine the threat level and response (assuming imminent deadly force present)
2. Step off line of the threat quickly by shifting your weight and moving your feet in the appropriate direction. This is wholly dependent on the threat. Someone with a gun in your face should be treated differently that someone a few feet away with a club. For now we are again assuming 0 feet of difference (chest bump)
3. at the same time of your shift, use your non dominant hand strike target in chest/stomach/throat/nose or any available target HARD while simultaneously shouting to distract him. Yea, it seems silly but going from the quiet victim to a raging tiger in their mind may gain you the split second you need for the next steps. Also if he has a weapon pointed at your this is the time to grab it, better lose a hand than a life.
4. Sep back with your right leg creating space between your hidden weapon and your attackers grasp and creating space to deploy the weapon.
5. Sweep back any clothing and draw your weapon, bring it up close to your body muzzle forward, elbow locked to your body with your arm pointing at the target.
6. Fire 2 rounds to center mass from this position, this should hopefully create some additional space between you and the target for the next step.
7. Bring the weapon up to eye level with a good 2 hand grip (if possible assuming the knife you may have grabbed for to distract him did not find cut you for example)
8. Quickly perform an OADA on the target to assume current threat, re-engage until target is not longer a threat.
9. Do a 5-10-25/360 sweep for additional threats.
10. Engage threats until no longer present.
I know this assumes a lot, especially that you are good enough to pull this off without taking one shot yourself, or that if the wolf in your face has a friend that they will just stand by while you punch and shoot their buddy without drawing their weapon.
I often practice this in my basement (minus the yelling) using a support beam as an improvised target dummy. Take it slow and don't rush your movements until you are comfortable. It is often said that "slow is steady, and steady is fast" - I think Mark Wahlberg used that line in Shooter.
Sometimes when talking to people I will mention a "360 sweep" meaning a situational awareness check of your surroundings. I used a training point from my last deployment to come up with the 5-10-25/360 sweep. In deployment we used 5/25 sweeps every time you stopped a vehicle to check 5 meters around your vehicle for IED's and then did the same thing out to 25 meters. I use 5-10-25/360 in this same context for sweeps as follows:
5 - sweep an area roughly 5 feet from you, this would cover people standing next to you or those able to lunge at you immediately.
10 - a 10 foot sweep that would preclude anyone just outside this range that you would have time to move away from to avoid.
25 - this area would include those persons who may be able to get to you before you draw your weapon while at a run, this is your reaction "bubble" I talked of before.
360 - sweep 360 degrees each time keeping your head "on a swivel" back and forth.
This type of sweep will identify immediate threats to you for OADA purposes. This should not be taken as an excuse not to do common sense sweeps of your environment at further ranges. If you are walking down the street and see a group of "ganstas" hanging out down the sidewalk or conducting some obviously nefarious business, avoid the confrontation well before your 25 foot bubble is broken.
Hey, this is just me talking here, if this makes sense and works for you by all means run with it. This is not meant to be taken as training advice "at large" and I assume no liability for its use in the real world. As with everything else in life, your mileage may vary. Each situation is different and will dictate a slightly different response. Be flexible to each situation, use the learned training you may have as a basis to work from, but be willing to adapt their application to each threat.
As Bruce Lee once said:
“Empty your mind, be formless, shapeless - like water. Now you put water into a
cup, it becomes the cup, you put water into a bottle, it becomes the bottle, you
put it in a teapot, it becomes the teapot. Now water can flow or it can crash.
Be water, my friend.”
