Exactly as expected - Streamlight TLR-7 HL-X 1913 Sub USB Multi-Fuel High-Lumen Rail-Mounted Light

I put this thing on my Springfield Hellcat Pro comp/a red dot and it fits great with the '5 key' and the light functions as it should, no problems. It doesn't make my gun "bulky" so it's great for concealing.

DON'T MAKE THE SAME MISTAKES I MADE BY BUYING THE INCORRECT RAIL MOUNT TYPE (such as 1913 Picatinny, Etc) Even tho it says on the product that they have the same "name" (TLR 7 HLX SUB) but not all have the same rail mount! So MAKE SURE YOU HAVE A 1913 RAIL and not something else you're mounting to even if it seems like the exact same product, which it is, JUST DIFFERENT RAIL TYPE!

If you got the correct rail mount flashlight for your gun and still doesn't seem to 'fit', you may need to change out the "key" with the number on it, to one that'll allow you to properly mount the light on your specific gun and that's shown in the manual. You should get included with the product a set of keys for your 1913 rail mount.
