Additionally, is it lawful for a qualified Colorado resident to purchase or receive delivery of a rifle or shotgun in a state contiguous (AZ, KS, NM, OK, NE, WY, UT) to Colorado as long as the sale fully complies with the legal conditions of sale in both states.
No, Colorado law does not require someone to be 21 to purchase a handgun. That is a federal regulation which applies to sales by federally licensed dealers.

There are no contiguous states provisions in Colorado law. Colorado residents may purchase long guns from licensed dealers in ANY state, as long as the sale complies with the laws of both states.

No one may purchase a firearm in a private transaction in any state except their own.
