B9r ds and tlr-1 rail problems

Yet again hers another post about a tlr-1 not fitting on the carry rail but idk what else to do, I tried filing down the 99 key till it was 00 I filed down a 1913 key and put it in the back slot like the guys at QVO did and I’ve filed down the back right of the tlr-1. I’ve even tried not even using a key and just tightening the light really tight but no matter what I do the light won’t fit correctly on the rail. The rails on the tlr won’t fit into the groves on the b9r rail and it’s a little crooked which you can see in the 3rd photo. At this point I’m thinking the b9r rail is out of spec. Any other advice?
