Figure I will update a bit here after a few weeks of patrol, dry fire and live fire sessions. I have been running a DFA w/ a non-RDS holster and QLS for a G45. I found when used on a DFA/QLS the NCP provided too much negative cant and kicked out the grip of the gun a bit too much for my liking. I found the grip to be in an unnatural position when working the draw from a POI/hands in front.
After talking with the guy behind the data (The Theory police), it sounds like the DFA levels out a non-rds holster about 5 degrees, and a maxed-out QLS another 3 degrees. In essence, it brings the holster to a much better position removing most if not all of the positive cant without anything aftermarket.
This brings up a couple of points I haven't recalled reading before.
1. The NCP is specifically designed for an RDS holster and according to TTP, a non-rds holster will alter the angles. Something to be aware of for those of us without an RDS policy.
2. The shooters position from the draw... All the testing appears to be from a standard arms relaxed by the side stance. I wonder if the data would be any different if tested from a POI? At least for me, it felt odd drawing a heavily negatived canted pistol from a POI. *Could very well be due to the DFA not allowing a proper 2oclock belt position and too much angle)*
