So I just got done trying the NCRE. Good product, very good indeed as it helped me present the weapon as I needed to...that said, and something for those of you right handed guys in particular...The NCRE was/is great when dismounted or if you are perhaps a passenger officer BUT...with it installed I can not draw my weapon while seated in the drivers seat of my squad car (Ford Interceptor Sedan). No way I could get the rearward movement required to draw the weapon-rearward movement of both my arm and the pistol, is blocked by the seat. Now, it most certainly can be due to my body type or other factors such as this vehicles seats but be aware of this before you try to stick on your belt and go to work.
Again, all life saving gear needs to be vetted BEFORE your life depends on it.
Great product for certain applications but at least for me, this is a no go for LE duties.
