Wolf's Range in Bristol has IDPA. So does Metacon Gun Club (NECPL). Somers Sportsmans has some really good club shoots. Rockville has a variety of action matches throughout the year.
Sprague Rod and Gun does IDPA every other Sunday. Bit of a drive from NY, but we put on a good match. Next Sunday is the next match. Check here for schedule.
