Thanks everyone for all the great responses. Mindspeed, I've already been in contact with G-code, and they do not currently make a holster for the HK45 with the addition of their "shroud". I got a light... an' I wanna use it.

However, they did say they "may" be making one in the future. I had a pretty bad experience with "Off the Grid Concepts", and simply want to make sure that if and when I throw down over a hundred bucks for a holster, it is what I need and want.
Thanks again, everyone.
Sincerely,
Kevin: a.k.a.- Book
p.s. Commiehunter, correct me if I'm wrong, but I was under the impression the Serpa only made holsters with light attachment for the Xiphos light? That's how I run my 1911.
