Yes, I've been talking directly to them -- a lady in sales. In fact, she just called me back and I told about all the posts here on the forum about confusion between the model numbers. She confirmed that they redesigned the holster for the Shield and the correct model number IS the 5ART. I ordered that today with two options -- the leather lining, which will make it slimmer, and a partial sweat shield in case I do occasionally wear it IWB instead of the pocket. She said the partial SS will still allow pocket carry without interfering with grasping the pistol grip. Total cost including the two options and shipping is $45.90. Will take about 7 days because the leather lining makes it a custom build.
As an aside -- I will use this holster probably as a pocket carry all the time. I have reservations that it will stay in place, on my body, as an IWB. Maybe I will be surprised, but the old saw "I am from Missouri, show me" is in play here. The only reason I added the SS was on the outside chance that I CAN use it IWB.
