On July 1st 2013 18-12-112 went into effect. This law restricts the private transfer of firearms in Colorado without a background check. So to be it quickly…
Before this law went into effect if I wanted to buy your gun we would just meet in a parking lot somewhere and I would hand you the cash and you would had me the gun. Most of us were wise enough to get a bill of sale and follow other good “private sale advice” but it was legal regardless.
Now, after this law going into effect, if I want to buy your gun we must do the transaction with someone who has a FFL (Federal Firearm License). This generally would mean going to a retail gun store. The FFL would perform the required background check on the buyer. The buyer will pay the new state fee (22.214.171.1244) and a fee to the FFL for their time. If the buyer passes the check then they can pay the seller and the transaction is completed.
I'm not aware of any court cases in Colorado so far that have involved this new law. There is great concern about how it may be interpreted and how it might be enforced. Only time will tell.
