You'll find that the only company that makes a drop leg for that combo is Safariland (6004 series). You'll still need to hog out the bottom to accomodate the bit of barrel that you have, but its pretty much the only option.
At this point I'm using a either a BladeTech UCH at 4 o'clock, but I'm getting ready to order a Raven Concealment appendix carry holster as well. A lot of it is going to depend on your body type and practice methodology (how much drawstroke work you're willing to put into it).Also, a personal preference question for the CCW's out there. I have a G26. Would you prefer a SOB, IWB, or OWB? I was carrying the G19, but my wife wanted a baby glock, got her the 26, and now I think I might switch over as well.
