Try to go the legal route, see what you need to get a permit for owning a gun, if your application is rejected, than you have to find an illegal way to acquire a gun, which is more difficult.
I would suggest the dw, but sources are limited when it comes to guns, there are very few ones out there on the dw that are legitimate, even then it's not guaranteed you will get it, depending on border controls, etc...
I know this answer is not what you are looking for, but hope you find what you are looking. good luck!
