I am back to refute one point of why Akai can not be Scar (as I believe he is for several reasons). You claimed that there is no medical evidence of brain injury causing a change in handiness and that is exactly what I found.
Pathological left-handedness: An explanatory model.Left-handedness (Under the part - Does being left-handed cause problems?)Granted most of this part is theory and about events before birth.
Probing Question: Can you change the handedness you were born with?(The answer by the way is YES
But in left-handers the right half of the brain is dominantWhy important. If Right(about how scar got his scar[Kir shot him grazing his right check]0, then Akai was shot so the right side would scar, and as the above shows that would effect his left side.
Right Hemisphere Brain DamageNote the following:
Memory: problems remembering information, such as street names or important dates, and learning new information easily.
Orientation: difficulty recalling the date, time, or place. The individual may also be disoriented to self, meaning that he/she cannot correctly recall personal information, such as birth date, age, or family names.
Attention: difficulty concentrating on a task and paying attention for more than a few minutes at a time. Doing more than one thing at a time may be difficult or impossible.
All these are thing that are associated with: Right Brain injury. See any of these in Scar?
Meaning such an injury could cause a switch in which hand one uses.

this passageTWO BRAINS--LEFT AND RIGHT HEMISPHERE
We have two eyes, two hands, and two legs, so why not two brains? The brain is divided in half, a right and left hemisphere. The right hemisphere does a different job than the left. The right hemisphere deals more with visual activities and plays a role in putting things together. For example, it takes visual information, puts it together, and says "I recognize that--that's a chair," or "that's a car" or "that's a house." It organizes or groups information together. The left hemisphere tends to be the more analytical part; it analyzes information collected by the right. It takes information from the right hemisphere and applies language to it. The right hemisphere "sees" a house, but the left hemisphere says, "Oh yeah, I know whose house that is--it's Uncle Bob's house."
So what happens if one side of the brain is injured? People who have an injury to the right side of the brain "don't put things together" and fail to process important information. As a result, they often develop a "denial syndrome" and say "there's nothing wrong with me." For example, I treated a person with an injury to the right side of the brain--specifically, the back part of the right brain that deals with visual information--and he lost half of his vision. Because the right side of the brain was injured, it failed to "collect" information, so the brain did not realize that something was missing. Essentially, this person was blind on one side but did not know it. What was scary was that this person had driven his car to my office. After seeing the results of the tests that I gave him, I asked, "Do you have a lot of dents on the left side of your car?" He was amazed that I magically knew this without seeing his car. Unfortunately, I had to ask him not to drive until his problems got better. But you can see how the right side puts things together.
The left side of the brain deals more with language and helps to analyze information given to the brain. If you injure the left side of the brain, you're aware that things aren't working (the right hemisphere is doing its job) but are unable to solve complex problems or do a complex activity. People with left hemisphere injuries tend to be more depressed, have more organizational problems, and have problems using language.

SKIN SENSATION
If something lands on my left hand, this information will be transmitted to the right side of my brain. It goes to the area of the brain next to the area that deals with movement. The tactile area of the brain deals with physical sensation. Movement and feeling are closely related, so it makes sense that they are next to each other in the brain. Because movement and tactile areas are located close to each other, it is not uncommon for people with a brain injuries to lose both movement and feeling in parts of their body. Remember--tactile information from the left side of the body goes to the right brain, just like movement and vision.
Note the highlighted words: Injury to one side effects the other side. While Akai might not seem to be hurt on his left side, his right brain getting injured may force him to use his right hand as Left hand is now the weaker because of brain injury.
Also A reminder that FBI agents are trained to use either hand when firing.
FBI Pistol Qualification Course and
The FBI: a comprehensive reference guide and
Pistol Qualification Course, 2009So Akai was trained to use either hand to fire.
