Recently I was working with a SWAT team that had just added two new guys that had not yet been to a SWAT school. We were just getting them accustomed to clearing rooms and then eventually entire houses with a pistol in their hand. Sounds pretty simple doesn't it?
The problem is that these officers like many other police and citizens who CCW have spent a lot of time on the range drawing, shooting, and moving, with two hands on the gun. This can be problematic when learning to do things such as opening doors, holding gear, using hand signals, keeping their balance, and moving people out of their way with the other hand. Due to what is called sympathetic reflex, when one hand contracts the other hand will do the same. This can result in negligent discharges. Another issue is that when both hands are glued to the gun it can force the shooter to extend his gun forward even when there is a non specified threat in front of him such as what appears to be an unarmed intruder that does no respond to verbal commands. I have found that many people's response to being "gun faced" at arms distance is to reach for the muzzle of the pistol. The more projected the gun forward the more likely this is to happen.
This occurred several times while training the new officers. From within a room or when confronted head on, I was able to take advantage of the officers having both hands on the gun and was able to sweep their pistol out of play. Of course I was immediatly dealt with by the officer behind them. A citizen clearing his home or business will not have this luxury.
Once they were taught that it was a handgun and not a handsgun and that while clearing with a gun it is a good idea to leave the reaction hand empty or to hold a light if needed, I was unable to take their guns.
It is a very natural thing to come task and tool fixated, you are amped up with a gun in your hand, upon encountering a threat that does not require rounds you squeeze the gun harder with both hands. If someone grabs the gun your reaction is to hold on as tight as possible to keep the gun, there is a good chance that they may also have both of their hands on the gun. Now you are both task/tool fixated. It becomes a wrestling match. Doing the same scenario but with only one hand on the gun you are not only able to step back drawing the pistol into your center and away from the threat but you can also use your other hand to push, pull, or swing at your attacker.
Being able to shoot a pistol and work with one in your hand are two very different skill sets.

Seriously: Are you saying that the games will cause me to stand 'frozen' in fear if bad things happen? 
The first time to get banged around with a gun in your hand should not be in response to a bump in the night at 0 dark thirty.- George
