Picked up a "We the People" holster for a Glock 19. I took advantage of some discount codes and got it for $23.80 shipped.
I know I'm operating near the bottom of the spectrum but hey- it's American made and I'm happy with the other one I picked up earlier this year.
Pros- Well made.
Fits the Polymer 80 frame well.
Adjustable cant brings the grip of the pistol to a more reachable position when carrying IWB in the small of the back.
The end of the barrel/slide is completely covered by the holster (unlike the Glockstore $35 holster-last picture)
Very economical
Cons- Retention is acceptable although you don't get that audible kydex "click" when the trigger guard engages the divots.
(I think this has to do with the slightly different design of trigger guard of the PF940C frame)
Mag release is not covered by the holster. I've heard different opinions on this-we'll see how it works.
