Would like to add a small, powerful, reliable light to my 43x? What are y'all using? Would love pictures. And what holster will accommodate the light?

TLR-6 with Vedder Light Tuck, yes it works fine with the light.

No pics, sorry but I have them for both my 42 & 43.

Not much in this category is 'powerful' (100lumens), but it's better than nothing.
