This version 2 of the TRex Arms Sidecar holster is for a Glock 19 w/Streamlight TLR-7A. I put two of Tier-1's small wedges on the back. It just wouldn't work for me. Unfortunately when you buy a holster "you pays your money and takes your chances". I've only used it a couple of times so it is virtually new. $75 seems fair.
