yours does in fact look to be good and tight for OWB wear.
im thinking the cant and curve as you point out is very effective forits tight in; and its construction looks top shelf.
id still add a strap & snap ( 30 minutes tops--I've done many) for more positive retention in active situations.
it looks as if you can change it to be IWB, though it would ride high.
does it have adapters for that feature--to lower it?
bears looking into, thank you.
