I'm not aware of any state with CCW that requires permit holders to carry unloaded. That just wouldn't make sense.
But some states with shall issue still have some rather silly restrictions, like not carrying in bars, churches, and so forth. Those places are private property and their owners are free to restrict carry and should be as free to permit it if they so desire, it seems to me.
Oregon's laws are the least restrictive among states that issue permits. Bars, churches, and so forth are not restricted by the state. Government entities are limited in what they can regulate. Schools can't even prohibit CCW in their (our) properties. And that's fine. If some responsible person wre exersizing their right on one particular day maybe Kip Kinkel wouldn't have shot all those kids, those kids of my friends and my coworkers at the school across town that day. Maybe.
But still, you have to fill out paperwork and pay a fee (tax) to the state to get permission to carry concealed gunz. That is infrigement, and I support nothing less than a repeal of all requirements for government permission to obtain and use guns. Gun control is rooted in racism and I don't believe in either.
