If you’re asking “how old do you have to be to buy a firearm in Colorado?”, the practical answer today is simple:
You must be 21 years old to purchase a firearm from a dealer (FFL) in Colorado.
Even though federal law still distinguishes between handguns and long guns, Colorado law and how dealers operate have effectively made 21 the minimum age across the board for retail purchases.
Federal Law vs. Colorado Law
Under federal law (18 U.S.C. § 922(b)(1)):
- 21 → Handguns
- 18 → Rifles and shotguns
However, Colorado requires most firearm transfers to go through a dealer under:
- C.R.S. § 18-12-112 (Universal Background Checks)
Because of this, the practical result in Colorado is:
21 years old is required to purchase any firearm through an FFL.
Minimum Age to Buy a Firearm in Colorado (FFL)
- 21 years old
- Required to purchase:
- Handguns
- Rifles
- Shotguns
- Frames/receivers
- Required to purchase:
If you walk into a gun store in Colorado, you will be required to be 21.
The Immediate Family Exception
There is one important exception.
Under C.R.S. § 18-12-112, Colorado allows immediate family members (parent/child, grandparent/grandchild, siblings) to transfer firearms without going through an FFL or background check.
This is not a loophole—it is a specific legal exception.
Can 18–20 Year Old’s Receive a Firearm?
Yes—this is where people get confused.
An individual who is 18 to 20 years old can generally:
- Possess a handgun
- Possess a rifle or shotgun
- Receive a firearm through a lawful transfer, such as:
- Immediate family transfer
Why 18 Matters
- Under 18 → firearm possession is heavily restricted
- At 18 → an individual can generally lawfully possess a firearm
That makes 18 the practical threshold for receiving a firearm—even though it cannot be purchased from an FFL.
