Honestly, I prefer leather.
I have always liked the forward cant pancake.
I have a Desantis for my 1911 < RIA CS TACTICAL >
And a Clament Custom Leather for my XDS.
All of them "hold tight"
For me an OWB holds the butt tighter than most IWB's.
I am 6' at 190lbs 55yrs old but my waist is smaller than my hips/belt.
The only disadvantage is that the OWB is a bit more prone to flashing the gun,
because the holster is outside the pants.
A long tee solves that for me here in Florida.
