That's why I went with a 3rd Gen G17 and G19 for low light classes, since I just had to order a BladeTech paddle for each of them.
There is a laser advertised that fits the Sigma, which also has a rail on the bottom so you can attach a light below it. Quality wise? Who knows. It's not a well known brand name product, so I'd be a little cautious about laying out my money for it. Also, it would put your light a lot lower than what would be easy to manipulate.
Basically, if you want accessories, you'll have to choose just about any other handgun than a Sigma. Oh, and don't blame the engineers on this one. They fought hard for a standard rail, but upper management thought it was a good idea to go the HK USP route with a one-off rail. That's what you get when you have people who don't know and don't care about guns in charge of making decisions about guns!
Sorry I had to break the bad news. The best thing you can do is to buy a used S&W Tactical model, or something like that, that's more popular, or maybe the M&P. You'll be able to find whatever you need or want that way.
