No such thing as "reasonable" only logical. That is a logic fallacy right there. Using the term reasonable or sensible as your argument is an argument based around emotional appeal.
What do I find as "logical" gun restrictions for legal and law abiding citizens for gun ownership? Easy...
1) Required background checks and registration. I do not mind as this is not an infringement upon law abiding citizens. So long as I can BUY any type of firearm, which includes full auto if I wanted.
2) Provide incentives for those willing to undergo firearm safety and training courses. This is not the same thing as forcing such training as forcing training as a means to "ownership" is an infringement upon ownership. Incentive would be some thing like lowering home owner insurance rates for those with legally owned and registered firearms in their homes as an example. Do not have higher rates for those that do not take training for legally owned guns in their homes without taking courses as that would be infringement.
3) Enforce laws that provide fines and actions against legal fire arm owners that do not take proper protections, such as a gun safe, for legally owned firearms that end up stolen and used in a crime. Most states have these laws, but not all.
That's pretty much it for logical "gun control" for law abiding citizens. Everything else is just fear mongering.
