Damn right they are!
Have you customized them any?
All of mine have the smooth trigger, I just prefer it.
I tend to put 3.5 connectors in all of mine.
I also like to do the 25 cent trigger job on them.
Other than that I reduce the trigger safety and re-contour the trigger guard just a tad and polish the rough spots.
I like for my finger to glide across the polymer...
