Recommendations for Ruger EC9s pocket carry holsters (with some retention)?

Similar to the Allen Spiderweb. The current issue is that the current holster doesn't hold the gun when turning upside down/extreme angles (I know this is a tall order). The Spiderweb size 11 holds sr9cs how I described, which is nice. via /r/CCW https://ift.tt/2LOMAG2
