Any problems noted using the standard molded Kydex or Polymer holsters with an OEM extended slide release? If so what works and what doesn't? I am inclined toward the Alien Gear ShapeShifter- of course neither they nor any manufacturer other than custom will guarantee fitment with non-standard guns. Do you think the release will be an issue or just go ahead, order and try it out with the 30 day return guarantee? I have the G48 Thanks for your input.
