'Had a hard time finding an IWB holster for the P07 w/ a light/laser, but I finally found one that looks like it'll do the job. It's different from the usual leather, nylon, kydex holsters. First of all, it doesn't use a clip, so this may be a good thing for some but may not work for others. I haven't received it yet, but it's the Series 10 from Remora Holsters:
http://www.remoraholsterstore.com/You can choose "Build Your Holster" and go through the wizard, then specify the color, light/laser/etc. At $16.95 + shipping ($6.20 to NY), it's rather inexpensive for what's being referred to as a unique, effective, all-American made holster.
I saw a few other brands of universal clipless 'sticky/tacky' material holsters that look similar and are getting decent reviews as well. I'll post a follow up once I receive it and try it out.
Edit: Forgot to mention that they do have ones that have clips as well.
