For an early father's day gift I received a pair of Pro Ears (Pro-Slim, Dimension 2). Not being particularly found of white I've decided to return them for a black pair. After reading up on Pro Ears product line I see there are other models available such as "Pro-Mag" and "Pro-Tac". Anyone with experience or knowledge of Pro Ears product line have any recommendations? I shoot .223, 7.62mm and my glocks (45 autos) but who knows what kind of cannon the guy next to me at the range will be shooting. My concern about the Pro-Slims is they are rated for smaller calibers and are not recommended for indoor range use without secondary protection using earplugs. –RR
