I started off shooting IDPA 1.5 yr ago. It's great. I really enjoy traveling around and shooting the state matches I've shot 5 major matches since I've started, lots of learning at each. Then, this year I started shooting USPSA. It's great also. I just returned from the Glock Only Match, holy s.
That was awesome. I also got signed up for the Area 1 match. Can't wait for that one.
Try them both. I like the control of IDPA but I love the freedom that USPSA offers. Trigger time either way!!
