I am confused. How does eye dominance correlate with type/location of holster? For that matter, how does that correlate with shooting positions?
While many people like cross-draw holsters, especially since it looks cool when you draw your gun, there are probelms.
1. You gun is already facing the wrong way before you start your draw, and the gun is going to have to be brought to level and pivoted 180 degrees to target.
2. Cross draw is slower for that reason since the gun and muzzle must travel further to be pointed at the target, assuming you are not trying to shoot someone behind you.
3. Cross draw is optimal for the person you are fighting in CQB as they can reach in, grab the gun and retract it only slightly before they can shoot you with it. It would be very hard to draw your gun and get it rotated in such a situation.
On a positive note, cross draw can be great for a car holster if you are the driver, but in that circumstance, there is little or no chance for a scuffle to develop over the gun if you are belted in your car.
