Check out Ravenconcealment.com - they can make you a holster that can accommodate your G19 with whatever model light that you tell them. A friend of mine has one and swears by it. I've worn it once and it was fantastic.
Yeah, I know what you mean. They make a fantastic holster though. Also check out www.sharktac.com - I visited their booth at a gun show last weekend and they make a very nice product as well. They were making holsters right there at the show so I can't imagine the lead time is that long.
