Also @Rams you're absolutely wrong. Finding guns through illegal means is NOT and will NEVER BE as easy as purchasing them legally. That's a quip that i have no idea why exists.
Look at it this way, weed has been made legal in states here in the US. This has now made it very easy to purchase marijuana. The old method was hitting up the various dealers you have in your phone, driving out to meet them often times waiting long periods of time, sometimes everyone is out of supply, sometimes you have to travel a far distance to make the purchase as growers are usually out of the metro, sometimes the quality is sub-standard. You see how all of these can be deterrents to you purchasing your marijuana? Even though there is a huge black market industry, it does NOT mean easy access.
Now try and imagine some difficulties you would face trying to find access to a good black market gun supplier.
