Currently, the law reads that open carry must be holstered in a shoulder or belt holster in the bill without any definition or other guidance as to what are the requirements or characteristics of a shoulder or belt holster. Therefore, it is my opinion that any holster that is connected to a person’s belt or is carried around the waist area should be considered a belt holster. Since a thigh or tactical drop leg holster is connected to a belt so that it doesn’t slide down the thigh, I would think that it qualifies.
However, that is just my opinion, there may be police, prosecutors and judges who have a different opinion. Only time will tell if we begin to see arrests based upon the type of holster a handgun is carried in. Hopefully the police will have better things to do and use their common sense and discretion before arresting someone because of their holster. Therefore, ultimately, if you want to avoid any potential hassle, you should carry it in purely a belt or shoulder holster.
Thank you for your question.
