+1 on the Andrew's leather!!
My G30 is my daily carry. She's been my constant companion for 7 years now. (My longest relationship!!)
Get some night sights. I have the green/orange Meps on mine.
And LOTSA range time!! Mainly because it's such a pleasure to shoot!!
Changes I've made:
-Ghost 3.5 connector
-Stippled the frame (not everyone's cup of tea, but I LOVE it, esp. when shooting outside in the heat)
Enjoy the GREATEST Glock made!!
