Hey, thanks for the ideas so far!
Yes, I'm definitely going with the Warren Tactical sight set with the fiber optic front. I believe the .215" is the proper height for the Glock 17.
Thinking about triggers, it seems like what I have seen so far is that it's really the connector and the trigger spring that make the difference? So one of the more expensive drop-in kits may not give me much extra benefit for a lot of extra dollars. If that is wrong, please let me know. Also, I realize that only a couple of the drop-in kits would be legal since an OEM trigger is required.
Grip tape is something I will need to look into--something like Falcon grip? Also, what is the benefit of using the plastic grip plug?
