An individual (as opposed to a licensed dealer) is not supposed to use the U.S. postal service to ship handguns. You are supposed to use a secondary carrier like Fedex or UPS. If the police department is in the same state, you can legally ship it to them, but if you ship and handgun to a different state, you are supposed to ship to an FFL (licencsed dealer).
No. ALL drugs (prescription or nonprescription) are restricted items, and may not be mailed via USPS.
What shipping service was used? If it was mailed via USPS Express Mail, it will be there the next business day. If it was mailed via USPS Priority Mail, then it will be there in about 2 or 3 business days (though this is NOT guaranteed). Items mailed via USPS First Class typically arrive in 2-5 business days (again, not guaranteed). Parcel Post (and similar services like Media Mail or Library Mail) typically arrive in 5-7 business days.
If mailed by the USPS the maximum time would be three days
Theoretically, according to USPS standards, on Monday.
No, they don't because it is a national holiday.
Yes
No... It cannot be sent through USPS to P.O. Boxes.
It depends on the type of package and I would say if it is mailed, or processed at the PS normally will deliver it, during their weekly regular schedule.
Depends on the gun. A rifle or shotgun that is unloaded MAY be mailed in the US Mail. See Domestic Mail Manual, section 14, restricted mailings. A handgun may only be mailed by a licensed dealer or manufacturer. If the OWNERSHIP of the gun is changing, other than by inheritance, and it is going to another state, the gun must be sent to a licensed firearms dealer in the state of the receiver of the gun.
no you would not be arrested
UPS, FedEx or US Postal Service. However, the frame of a handgun cannot be mailed.
No. An air pistol (or CO2 pistol) that has enough energy to be usable as a weapon may only be mailed by a person holding a Federal Firearms License as a dealer or manufacturer of firearms. While Federal Law in the US does no treat an air pistol as a firearm, the USPS Domestic mail manual classes them as a pistol, and restricts mailing.
