I've had my NCP-E on my SLS/ALS RDS holster for a little over a week of uniformed patrol including two dry-fire sessions and a full day of live fire training. I am a big fan. I am consistently seeing a .10 second reduction in my draw time over normal. I am currently running it with the least amount of negative cant and I have the holster positioned directly over my hip pocket. This is also my first experience with a holster mounted CAT. It looks a little odd but I really like how easy I can grab the TQ with either hand and it basically takes up zero space on my belt.
I just ordered two more for my other holsters. Thanks to everyone who contributed to bringing these to market.
