I prefer a nice kydex OWB that hugs the body. Problem is, they're only meant for one gun so if you sell the handgun and get something similar in profile, it won't fit like a leather would.
So my main carry method is a leather belt loop OWB with body shield and...this is important...flat inner face. Interestingly the Paraguay-made Tagua is quite well made and will probably be my go-to from now on. It 's a democratic country well known for their leather artisans.
