Has anyone tried out the Versa Carry "holster" ( VersaCarry — Revolutionary New Concealed Carry IWB — VersaCarry )? All the reviews I have read online seem to have the same concerns about retention, and guarding the trigger. Can anyone lend any first-hand experience with the first or second generation of these "holsters" (the second gen seemed to have addresses most of the issues discussed in reviews)? I just don't want to waste my money if it's crap.
