Short answer, yes it is.
Long answer is, it really depends on where you are in the country.
In my area there are several 3 gun matches, mostly on Sat while USPSA is Sunday.
Several of the 3 gun matches have quit advertising them due to what I call burn out, I am seeing the same thing in USPSA.
A small group is doing all the work, people show up stand around watching them set up then shoot and scoot.
