I have been reviewing previous posts on hearing protection and have decided to get a pair of the Pro Ears. My question is: which one is right for me - the Pro-Slim or the Pro-Mag? I shoot a variety of guns, but mostly handguns (9MM, .40, .357 Mag) in IDPA matches and an AR-15 in military rifle matches. Also, I sometimes participate in sporting clay matches. I would like to get a pair of muffs that are the most comfortable. Will the Pro-Slim model be enough for hearing protection with these guns? Keep in mind that I don't mind adding another set of in-the-ear plugs when I shoot my larger rifles (e.g., 7MM Mag). Thnaks in advance for your suggestions.
