Thanks for the help, I'm reading through it all now. I've got another question. Given the following definitions does this mean that the "Judge" handgun (and it's bigger cousin the "Raging Bull") would actually be considered a "sawed off shotgun" under Oklahoma law? The big thing to note would be the term "series of projectiles"
1289.3: "Pistols" as used in the Oklahoma Firearms Act of 1971, Sections 1289.1 through 1289.17 of this title, shall mean any firearm capable of discharging a projectile composed of any material which may reasonably be expected to be able to cause lethal injury, with a barrel or barrels less than sixteen (16) inches in length, and using either gunpowder, gas or any means of rocket propulsion, but not to include flare guns, underwater fishing guns or blank pistols.
1289.4: "Rifles" as used in the Oklahoma Firearms Act of 1971, Sections 1289.1 through 1289.17 of this title, shall mean any firearm capable of discharging a projectile composed of any material which may reasonably be expected to be able to cause lethal injury, with a barrel or barrels more than sixteen (16) inches in length, and using either gunpowder, gas or any means of rocket propulsion, but not to include archery equipment, flare guns or underwater fishing guns. In addition, any rifle capable of firing "shot" but primarily designed to fire single projectiles will be regarded as a "rifle".
1289.5: "Shotguns" as used in the Oklahoma Firearms Act of 1971, Sections 1289.1 through 1289.17 of this title, shall mean any firearm capable of discharging a series of projectiles of any material which may reasonably be expected to be able to cause lethal injury, with a barrel or barrels more than eighteen (18) inches in length, and using either gunpowder, gas or any means of rocket propulsion, but not to include any weapon so designed with a barrel less than eighteen (18) inches in length. In addition, any "shotgun" capable of firing single projectiles but primarily designed to fire multiple projectiles such as "shot" will be regarded as a "shotgun".
1289.18: A. "Sawed-off shotgun" shall mean any firearm capable of discharging a series of projectiles of any material which may reasonably be expected to be able to cause lethal injury, with a barrel or barrels less than eighteen (18) inches in length, and using either gunpowder, gas or any means of rocket propulsion.
B. "Sawed-off rifle" shall mean any rifle having a barrel or barrels of less than sixteen (16) inches in length or any weapon made from a rifle (whether by alteration, modification, or otherwise) if such a weapon as modified has an overall length of less than twenty-six (26) inches in length, including the stock portion.
Now I know that they get around the 1934 NFA because the barrels have a shallow rifling (as smooth bore pistols are subject to the NFA, or at least that's how wikipedia says they get around it), but the Oklahoma law doesn't say anything about rifling or the lack of it to determine the type of gun it is. I know they're sold here, but is there any reason I'm missing for why they wouldn't technically be considered sawed off shotguns?
Alright I came across another question. In 1277 it talks about unlawful places to carry. It dosn't directly talk about banks. I'm taking this to mean that it's legal to carry into banks and that no-gun signs aren't legal (except for places where it's already illegal like schools). Gah I hate reading legalize.
