Want to share that I recently upgraded a couple of JMCK IWB holsters with the JMCK steel clip. I had experienced situations with the plastic clip becoming insecure over the belt when driving and getting in an out of the car etc. The steel clip is the same form as the plastic one but it has retained position for several seeks of use and is indeed more secure. I highly recommend it over the plastic one.
I have to de-gun / re-gun over the course of the day depending on location and this steel clip has been great. The snap loops are fine but sometimes are difficult when in the car etc.
