Thanks for the review and the comments guys.
Everything you've mentioned is coming.. when time and capital allow it. RMR's, Beretta's 320's etc!!! As to the WML holster its a ways out There are some safety issues I have with I have with holsters built for them, it is easy to get something in the holster and near or on the trigger ( local LEO units have had Several AD's with the gun in a holster that accommodates a WML. seatbelts and other things have got in the holster and activated the trigger.)
The Cornerstone has a LOT of great design features!! here is a video we did on it.
