If you check in the LE subforum there is a significant thread about Safariland cant solutions. Long story short- either add a QLS system or safariland just released a CUBL shank that allows you to adjust the cant. For the muzzle end digging in I use an angled neoprene wedge left over from a AIWB holster I dont use anymore- Velcrod to the inside of the shank.
