Do I need to join the USPSA to shoot the matches?

No, USPSA membership is NOT required for our “Level 1” monthly club matches.
Only the Level 2 and 3 tournament matches require a USPSA membership. E.g. - Great Plains Sectional Match near Omaha and Area 3 match in Grand Island.
Membership information can be found on the USPSA.ORG web site.
