I know this subject gets posted a lot on other forums but I'm new to firearm purchases and I would like to know how the process goes.

1. Do we have to do background checks from like a purchase from friend or Armslist deal in the state of Colorado? I remembered my brother-in-law having to do a check when he purchased his firearm from the Tanner Gun Show years back.

2. How do I safely purchase firearms from deals like Gunbroker? I've read stories of how people get real close to being scammed. I have used Paypal in the past before, would that work? What are the preferred payment methods in this scenario?

Thank you for the help! :D
