I found out last evening that Eugene Yap's (principal) team is now designing a second generation I/OWB that will use a MILSPEC nylon (the same type used on rigger's belts) and velcro to take place of what I called the "J-Hook" in the review mentioned above. Additionally they plan on having a next generation loop attachment that will make the setup even more discreet and providing more concealability.
The team is striving to give the operator greater flexibility for their carry while making the holster more secure, quieter, and importantly - more concealable.
Sounds like a great start to us.
We will keep you up to date as we find out more.
