Help me understand the Organizations

[Romer]

There are a lot of groups out there to join

NRA - Member
NRA/ILA - Investigating on Donating http://www.nraila.org/gun-laws/state-laws/colorado.aspx

There are other groups that seem good to belong to, but joining all can get kind of pricy. Help me undertsand the groups below, the ones I missed and why they are good to belong to. I would like to understand why one would be better than the other

• There is the Rocky Mountain Gun Owners http://www.rmgo.org/
• Colorado State Shooting association http://www.cssa.org/news.php
• Civillian Markmanship Program http://www.odcmp.com/
• Firearms Policy Org http://www.firearmspolicy.org/
• Gun Owners of America http://www.gunowners.org/
• National Association for Gun Rights http://www.nationalgunrights.org/

All are probably good groups. Being new to the groups and NRA and owning a 9mm and AR-15, wanting to know which are the best to follow. Any I am missing that are worth looking into?

Course then there are the Clubs (Looking at Centennial Gun Club) and ranges memberships etc.

Thanks in advance for sharing your knowledge with me
