I belong to Middletown, http://www.middletownsportsmensclub.com/
. Great place in my opinion.
Fairfield is just a 10 minute drive for me, I didn't join because A LOT of members left when they shut down the rifle range. I have been there as a guest before. Seems to be ruled by the shotgun crowd.
I drive 30 minutes to Middletown, no regrets.
