I bought a set of ProEars through the program. They sell for about $300 normally, and I got them for $200. Still steep for electronic muffs, but they are very good. They amplify quite noises and suppress loud ones. They don't shut off the boost when a loud noise is heard, so you can carry on conversations even with lots of hun shots going off. You can also plug your iphone into them when you're working outside with loaud yard equipment and what not.

Didn't think to look if Kahr was on the list when I bought my PM9 last month, but I got it with XS Big Dots installed for only $599, so I'm happy with the deal I got. I don't think the Instrctor discount would have saved too much more than that.
