All I know is that I bought a Bladetech UCH and it was horrible -
Not comfortable, not concealable, not practical
For IWB I only go to Crossbreed and Comptac
Does it have to be "IDPA Approved"?
ETA: Just checked Comptac - they don't have FNPs listed, I would email them - I consider them top of the line.
I'd get the CTAC model, or the MTAC model
Good luck choosing!
