In CA we have different dates for Bow, Pistol, Black Powder and Rifle.
Texas has plenty of WMA public lands that are gunfire, handgun(the law says handgun not pistol) and shotgun only. Texas defines handgun specifically and AR pistol with a brace AND a grip that you can use your other hand with is not a handgun which must be capable of being fired exclusively with a single hand. Without the brace and with a heat “shield” a 300AAC or 7.62x39 as long as it is under 26.5” total length and you can hold it up and fire with one hand is perfectly legal on those WMAs I built a 300AAC with a can at 24” no brace and a keymod heat shield with no rails not hand grips specifically for those WMAs
