I recently got a Snag-mag pocket mag carrier. It's neat in that it disguises your magazine as a pocket knife - something that can be seen in everybody's front pocket around where I live. However, it's not perfect. I find that I rarely use it because I'm too paranoid about the magazine falling out of the mag carrier and me leaving it on a chair somewhere. I added some silicone glue to the inside of the thing to aid retention, but it's still not perfect. The pocket clip can rotate around a central axis, and possibly cause the whole thing to lose retention and fall out of your pocket. I'm thinking about getting an IWB mag leather carrier, but really don't want to stick anything else inside my waistband.
