I run a Streamlight TL3 on a Sig 2022 and I like not having 2 things to hold on to. My thumb of my off hand is naturally right by the switch so it's easy to control. I've heard a lot of good stuff about the new Inforce PML, and I'm ordering one of their WML's very soon. I'm going to have Harwell's make an IWB leather/Kydex holster for my Sig very soon.
