Thinking the TLR-7 Sub since there are G43X holsters that supposedly work with it. Still need to decide on a dot too since they didn't have complete guns with them.
I dont have one that I keep on my Micro, but I have a Micro and a 43x and swapped my tlr7 sub from my 43x to the dagger and it is basically the same. It would be a great light to put on a Micro dagger
