Recommend the Ava for the G19. I know quite a few ladies that are VERY happy with the Ava carrying a G19.
The Ava is my next splurge purchase. I have a standard Theis IWB for my G19 & G26. Use the theis holsters for all our carry guns. Have always just gone basic
Ava's the fancy holster that I'm adding to my collection. If you are ever on GlockForum (a sister forum to this forum) you can read quite a few reviews on woman CCing glocks 19's.
Hope this helps
