Cs Go Droping Weapons

Hello, I recently got a Razer ViperMini and changed one of the buttons to the play/pause media function. The problem is when I use it in Cs:Go, the media pauses and plays on command, but my weapon also drops. I did some testing, and it seems like the source engine reads the play/pause function as (something)+G. I will not accept changing the binding as an option because I have 3k+ hours of muscular memory of this game, and I am not willing to learn it all over again. I tried it and it was not a very good experience. Does someone know how to help me with this? Thank you anyways!
