Tangle is right about the Rock Steady Belt, as well as the Slide Guard. As I said in my previous post, I've been using HN Holsters including Slide Guards for quite awhile......the Slide Guard and Rock Steady Belt go together like "peanut butter & jelly"! RS belt holds Slide Guard even tighter to the body. I ordered a slide guard the same day I ordered my Sig p239, which came in today.....as a matter of fact, as I'm writing this, I have the 239 wrapped in a ziplock bag with the tension srew tightened all the way down in it's slide guard......that way, it'll be ready to go in the morning! I have a lot of good Holsters but can't say enough good things about the HN Slide Guard.....Great OWB holster!!
