I carry mine in either an M/D Ent. BS-2 Belt Slide or a Bladetech IWB (kydex). It works very well for me. The G30 has a consistent trigger pull, simple design, is very reliable, sweat won't hurt it, is fairly ugly (can't have everything), and, most importantly, fires .45 ACP. I'm partial to 1911; but, G30 is very practical for CCW.
Take Care!
