I was into the idea of them until I saw a youtube reviewer flexing the frame with two fingers when the mag was ejected. Seemed flimsy. Haven't tried one so that's just my two cents, something to look into deeper if it's really of interest to you though.
If you go for it, two things you have to do with any Glock - better sights, (i always put the TFX tritium fibre optic on mine) and a better trigger like a Zev.
There is a thin "shim" type plate for mounting, I used the CHPS plate.
Does the TLR 7 sub fit correctly on the front rail? ...
Yes, the G48 rail is narrower. That's why they made the TLR-7 Sub, which fits on rails narrower than the "standard width" TLR-7.
... I’ll either go with the TLR 7 Sub to the Olight baldr Mini for mine.
