I dont see how it could work out. In order to actually get the gun, you have to have it registered to me. And well if the gun is registered to you, how can the lending gun company be able basically sieze the gun back every year?
As it stands they really couldnt it, registration stays in your name till you sell it, so 1 of 2 htings would have to happen.
1, all gun laws be changed so that the firearms maker can legally seieze any gun they want at any time.
2. the loaning gun company would be quilty of straw purchasing if the gun stays registered to them...
Theory says that if a new model/mandated government add on like say mandatory electric gunlocks is passed by the government, any of the loaner guns could be siezed by the factory adn replaced with the new requirements putting lives at risk.
And what about a loaner car when the car is at the shop? Id hate to be loaning a SW Performance center 44 magnum and get stuck with a lorcin or jennings in 22lr for 8 months as a loaner gun.
