Never had one, never felt the need. I was just wondering what all the fuss is about.
I have shot all manner of rifles over the years, I have small hands but reach is not a problem for me. I tend not to grip the pistol grip as I find this is another point of inconsistency that I can eliminate. Instead, I basically hang my trigger hand by thumb around the area above the pistol grip (thumb forwards if stock allows) and my trigger finger on the trigger - that’s it, no other point of contact with trigger hand.

It sounds unorthodox, but I would be interested to hear how others get on trying it. Go on, humour me - 50 shots keeping everything else the same as you would usually shoot.

In the meantime, I may order a set back trigger, see how I get on.
