+1 for what Dgun said. Go to the source for the RIGHT answers. For all you know, I am 12 yrs old, and Mom does not know I am on the computer!
Yes, there are rules for 01 Dealers that transfer a gun to their private collection FROM their stock, and having a not-for-sale private weapon on their licensed premises, and selling a personal weapon outside of your license.
Yes, there ARE provisions for inheritance. Again, discuss this with Firearms Branch.
However, I will offer some free legal advice (which is worth exactly what you paid for it) IF you are going into the business. You need to incorporate. Probably a LLC. This insulates your PERSONAL assets from the liabilities of the business, the business OWNS the stock, etc. Not an expensive process, and worth it.
