There is no waiting period when you buy a gun in Texas. You do need a valid state-issued ID.
If you want to conceal carry your handgun, you must have a concealed carry permit. To carry your handgun openly by using a belt or shoulder holster requires a permit. You can carry your handgun, loaded and within reach inside your vehicle, without a permit if you keep it concealed. Rifles and shotguns can be open-carried without a permit. You do not need to conceal rifles or shotguns in Texas.
In Liberty Safe’s home state of Utah, you don't need a permit to buy or own a handgun, shotgun, or rifle. You need a permit to carry a concealed loaded weapon, and of course there are exceptions to where you're allowed to concealed carry a firearm: airports, courthouses, prisons, post offices, etc.
You don't need a permit to transport a handgun inside your vehicle, as long as it's legal for you to have the gun, it's not in plain view from the outside, and it stays locked securely in the vehicle (or in a locked container attached to the vehicle). It's not legal to carry a loaded long gun in your vehicle, though.
And remember that gun laws can change, so anything you find published online (including this article!) could be outdated. You should always check your state's government listing for the latest laws in your state.
