I carry mine several ways..for OWB, I use a JIT Slide holster made by Don Hume. For IWB carry, I have several..summer comfort, uncle Mike's..BUT..the most comfortable and highly recommended IWB holster, IMHO, is the CrossBreed Supertuck Horsehide Holster. Once you put one on and try it, you will never look back. And they have a 30 day try it guarantee to boot.
Garrett industries, holsters, brigade gun leather, and PJholsters, Im waiting on my holster from Brigade gun leather since last Feb LOL.. been using my Garrett to carry my G30SF for several months now and its very nice and comfy its the silent thunder IWB..
Try TommyTheisholsters out. I have one for my 23, soon for my 30sf and i love them. I even broke one of the kydex clips and he sent me to metal ones. I wanted metal. Anyway, awesome customer service! dare to compare!!
