LAKEWOOD - Like many big-ticket items, guns are a popular purchase for Coloradans on Black Friday.

The Colorado Bureau of Investigation reported it was on track to perform 4,000 background checks Friday on people purchasing firearms.

In 2011, CBI's InstaCheck unit set a single-day record by checking 3,031 gun buyers.

The CBI checks gun buyers against a mix of seven state and federal databases for criminal records, a process that takes less than four minutes on average.
