Good options for OWB carry? How about ammo? I've got some Hornady 124gn. XTP's for now. What say the 'fire?
Something that rides high on the belt tends to work best for sub-compacts in an OWB. My favorite OWB's are either the Pancake or Askins Avenger from HBE Leatherworks. Another really good option for OWB is the El Paso Highside or Street Combat; two great OWB's for sub-compact pistols.
As for load, you've started off with a very good one. I say any 124-147 JHP from any of the major makers will get the job done quite well.
