I just got a new P320 compact in 9mm I love the gun but I am having problems shooting low. From all the info I have obtained from here I know they sent me the wrong front sight installed (#6) and have decided to contact Customer Service and ask for a #8 front sight free of charge. Does anyone have any advise on how to ask. I also need the cust service email for some reason I can not get through to them calling. I really appreciate the help and feedback thanks.
