Good choice. I love my 45 Shield. Can't help with a OWB, I use a IWB comfortably. Light enough to forget it is there.
I put a Hogue HandAll grip sleeve on mine, adds a little grip mass. Hard to slip on but some Windex lubricant helps, maybe heat it up in some warm water. Trigger not as good as a Kframe, but it breaks in some.
Don't know if you want leather or kydex. I've got an owb kydex holster made by 'On Your 6 Designs' that I have been very happy with. I actually have several of their holsters and the execution of the design is very good, price is very reasonable and delivery was reasonable. I actually have several of their holster for numerous guns.
No they won'tWill the Shield .45 2.0 and the Shield EZ9 fit the same holster?
I use the DeSantis Mini Scabbard (?).
I use a Kramer pancake OWB holster and I am extremely happy with it. It's pricey at $126 but worth it.
