I shoot a lot of USPSA, 3-gun, and even some PRS. Two years ago I treated myself to a set of custom molded SoundGear in-ear electronic hearing protection. Got them from a fellow USPSA shooter who runs House of Hearing in St. George UT. I can send you his contact info.
The best news is when I checked with House of Hearing my insurance covered the entire price of the ear pro. Then again I work in a job where hearing protection is often required...
