Finally got a chance to wear my new Monica Kuehn CSO today. Along with a RC1 mag holder. Only got about 10 hours on it so far but Im very happy with it to this point. For starters the customer service is great. I received the holster within the quoted time even though she had to order in a mold for my gun. And she kept me up to date on the status via e-mail so I wasn't left wondering how long I'd have to wait. First thing is it looks great! Quality is excellent. It's stiff enough to be very stable and stays tucked in tight. Retention comes a little tight for my taste but Monica includes directions on how to work it in a bit and adjust the retention. So far it's the best OWB I have used. The mag holder is also top notch. Perfect fit. I'll post some more thoughts on it after a good month of use. Here are a few pictures of it with my Glock 36.
