Oklahoma passed open carry back in March of last year. Went into effect November 1, 2012. I tried it. I like it. Open is much more comfortable than concealed. My normal attire involves a tucked in shirt, typical business casual. I've gotten a couple different IWB holsters. In both cases, I've tried tucking in my shirts and found that I have a very hard time clearing the shirt off the holster in one pull. I don't feel safe with the gun tucked in. I've pretty well decided to open carry. I'm looking for advice on open carry holsters. I carry an XDm 9mm Compact. I am now using the paddle holster that came with the gun. I'm sure there are better holsters out there. I'm interested in improving weapon retention. I do not currently carry around any spare mags, but I'm considering wearing the 2 mag holder that came with the gun as well. What the heck, in for a penny, in for a pound. Any suggestions on mag holder(s) are also welcome.
