OK, so I have been following this subject outside of the forum in the periphery. My initial reaction to an after market belt mount was not very favourable. It was tempered when I saw that Safariland was coming out with a new UBL to address the issue. My initial skepticism was based on experiences I saw when members of my previous unit (UOF - LE) were starting to deviate in teaching to wear the duty holster (at the time the Safariland Raptor in Level 4) at the pant hem line (side of hip) and move it slightly forward. Somewhere between side of hip to mid way, just before an appendix carry. They were fine during draws without any stress or time constraint and choked when you added stress or time. Moved the holster back to side of hip and the draw smoothed out.
So this brings a completely different approach now. That said, I am a shooter and have been for a long time. I did learn rather early on that being a "shooter" isn't a major part of policing - especially in Canada. With that said, my concern is a phenomenon that occurs in the LE UOF world....that of silos/empires. All too often I have seen instructors become linear in thinking, especially when it comes to UOF training and the various sub-disciplines of DT/FA/Scenario-officer safety/IRD/TASER/Carbine/Shotgun instruction. The biggest issue is usually between the DT/FA world. I have seen too many instructors in each respective area become so good in their areas that they "forget" about the other areas.....and end up developing/forgetting that the range is a DT room with live fire and the DT room is a range without live fire concepts. Cross training and validating becomes critical to user techniques, so that they don't have unintended negative consequences when it comes to the other disciplines.
I am seeing the benefit of the adjustable cant on the duty holster. My opinion is reserved until more study and fleshing out is done in the DT room and during handgun retention drills, and more importantly in the the House of Pain - the sim house (no not just simunitions, but also protective suit training added in - blauer suit).
