Around mid-morning today, I ordered a mag pouch from Black Rhino Concealment. About 3 hours later, I received email with tracking info!
I've bought an IWB rig and mag pouch for a P30L from them before. Good quality kydex. I recall it being shipped quickly, but not that fast. They don't have too wide a range of products, but if you need something quick, I think these might be your guys. https://www.blackrhinoconcealment.com
