I would like to put a smooth trigger on my 26. Glockstore.com happens to be right by my house. They don't have anything that specifically says "smooth trigger," but they have different triggers for different glocks.
If you don't need the grooved trigger, put it up in the "free tag-pass it forward" section. I have a dedicated rimfire AA conversion kit/frame and it has a smooth trigger. My son (who loves this .22) asked if he could have a grooved trigger instead of the smooth.
Only if you wish to depart with it.
