I have carried my C9 many times. I purchased a *lovely* owb holster from Blade-Tech, and can highly recommend them. My only "complaint" is that it profiles larger than I prefer for a side carry. I have a CC shirt where the gun is Velcro stuck under the arm, and it works nicely. I have an order being verified with Cleveland's Holsters (A new user/business here on SteyrClub) that is making IWB holsters. And to be specific, he is making one that supports the C5L green laser from Viridian which I have. (Always learn to use your iron sights first, without fail!)
I look very, very much forward to getting it from CH. I want my Steyr for my daily carry and I carry every day I step foot out of my house.
