As far as the first video goes, it looks like maybe he's using the one built for a light without a light on the gun? Mine's screwed together, and fits a lot closer to the gun. It's also made out of a very stiff material, so I couldn't come close to twisting it apart like that. I do have the "sportster" model, so maybe that's the difference.
As far as the release goes - where they were using the same exact setup I have - I guess I've finally found an advantage to stubby fingers
. My fingers are short enough that they hit the release as intended, so the curling is a non issue for me.
But, it does see that there are definite issues with the holster. I'd probably think about picking something else up if it was the rig that I used on a daily basis.
