While most civilian gun carriers know how to shoot and hit their target from a distance – only a few have the skills to use their guns at very close range. In case you get attacked in close quarters, would you know how to fight with your pistol in close combat? (h/t to SurvivalSullivan.com)
There is no need to give up practicing fundamental shooting skills. Guns were designed to engage distant targets first and foremost.
However, you must seriously consider taking up contact training in a peer or group environment. You need to prioritize getting your gun into action at extremely close range with the right shooting technique.
At the same time, you must know how to protect your pistol from getting disabled or captured by your attacker, who might know how to use the gun at close quarters.
