IDPA (International Defensive Pistol Association) competition is a great opportunity to improve your gun handling and marksmanship skills in a safe and fun atmosphere. The courses of fire are intended to simulate real life scenarios where defensive shooting may need to be employed. IDPA style shooting is based on equipment you would carry on a daily basis rather than equipment specifically made for competition and/or speed. 

We hold Tier 1 Club matches on the 3rd Saturday of every month year round weather permitting.  Additionally, we hold Introduction to IDPA sessions with a live fire practice session periodically for shooters interested in learning more about defensive style shooting. Preregistration on PractiScore is required for both Introduction to IDPA and monthly matches.

In order to shoot our matches you must have either experience shooting IDPA or USPSA match’s previously, attended the GOAL Intro to IDPA course or attended an Old Colony Intro to IDPA class. If none of these qualifications apply to you please contact our OCSA IDPA Staff to see if accommodations can be made

Sign up for IDPA Email to make sure you receive the monthly match registration link.

See the clubs event page for upcoming IDPA events.

Anyone interested is invited to attend. The Introduction is made up of two sessions, a dry-fire only 2-3 hour classroom style, and a 3 hour live fire session where you can practice your safe IDPA gun handling skills.

 CLASSROOM SESSION - We will be demonstrating skills needed to participate in IDPA. Please bring your equipment to the classroom session with you EXCEPT AMMO - NO AMMO AT THIS SESSION. If you don't have equipment feel free to come anyway!

LIVE FIRE SESSION - Held the Saturday (weather permitting) following the classroom session. Equipment is required to complete this portion of the class.
