I got a relative that seems to handle a semiauto carbine much better than a pistol, revolver, or shotgun. She has a hard time operating a pump action shotgun, she limp wrists any pistol over .32 caliber, and even a .38 revolver hurts her hand. However, she never has a problem with a carbine and seems to shoot it far more accurately than all the other choices. My question is if she ever used a semiauto carbine to defend herself whether an AR, SKS, AK, etc, is there a serious disadvantage legally to this? Has using a carbine ever tipped a prosecutor's decision to prosecute or a jury's opinion?
