This morning I bought a VP9 Grey,my first HK in many ,many years.I changed the grip panels and cleaned,left the slide locked back,probably until Monday.I carry a Glock 19/4 or a 43 as my EDC. They have a great sale on and I could not pass this up. I did the on line warranty,as I have read this is mandatory if you need repair.This forum helped me decide to purchase the VP9 and I thank all for the knowledge you have passed along.
