I only have the 500 so can only speak to that model.
I've found that it's best to holster the gun prior to putting the holster on because
the soft leather "pouch" isn't very user friendly when it comes to holstering.
I'm comparing this to my Galco Ankle Glove, which is more "holster-like."
I generally ankle carry while wearing boots that are the same height as "high top"
tennis shoes and I've found that the leather of the Renegade rubs against the
top of my boot and makes a light, leather on leather, creaking sound when
I walk, whereas the Ankle Glove, shown above, doesn't.
As far as concealability is concerned, I see very little, if any, difference between
the two styles shown above with the type of pants I wear.
Another reason I prefer the Galco is that it has that slight contour on
the elastic in line with the gun, which tucks nicely into the top of
my boot and helps keep things in a positive location.
Sorry that I couldn't address your question(s) as far
as the different Renegade models are concerned.
