I think that would be better for sure.
I just ordered one of the DSG kydex models to try out. I believe the important thing is having cuffs on you, regardless of how they're carried. It's a running joke during our DT training that, after we get the 'suspect' on the ground in submission, we simulate unlocking our trucks with our key fobs and yelling, "Help, I'm a ### agent! Please get my handcuffs out of my center console!"
