Gun Randomly fires single time with Controller

While actively playing (happens on redsec, portal, firing range), my gun randomly fires a single bullet. I am not pressing the trigger nor do i have custom bindings. I have tried different controllers which does the same thing. I have monitored joy.cpl and haven't seen any unusual activity in the trigger. I have reset all my controller settings.  I have gotten this issue to occur just be walking forward only holding left joystick, but cant consistently replicate it. I have reset steam controller settings, updated drivers. I have disabled "flick" settings. I have completely unplugged my mouse and keyboard. I have changed my trigger sensitivity. 

Nothing seems to work, except when I play Mouse and Keyboard i do not have this issue. 

I believe this is a bug introduced in the update that happened either 6/17 or 6/18 (can't remember the exact date i had an update).
