Trigger guard - Strike Industries Billet Trigger Guard w/ Finger Rest

This is the second strike industries cobra trigger guard that I have purchased. The first one was installed on a ruger which has a slightly different trigger guard mounting design. The trigger guard only comes with 3 screws and I needed a 4th on the ruger. I contacted strike industries customer service about needing a extra screw and they completely ignored the emails I sent. I've bought quite a few strike industries products and this is the first time I've had to contact customer service about something only to be ignored. I don't have a problem with the trigger guards I like them but had to go out and purchase 4 new screws so they would all match. The one I installed on my psa only required the 3 screws so I was good there.
