Glock 9's and Trigger Reach

[Sippo]

JR, Would you know of anyone who has had success shortening the trigger reach on the 9mm Glocks through polymer stock modifications. (My pistols are for concealed carry self-defense and I'm hesitant to modify the trigger behavior for forensic reasons)

[JR]

You are asking a question that has no answer because one will negate the other!
1) Can I modify the frame to reduce the length of trigger pull (yes)
2) For forensic reasons, once a gun is modified it will remain as such (modified) forever
