You have a ton of options. I use a Fobus Roto paddle holster for details travel to and from work. Not the greatest for concealment though. Cost about $20.
You cant go wrong with DeSantis brand holsters as well as Galco. They both offer holsters that will work for you. I have several of both brands and have 0 complaints. Expect to pay $60 or m ore for them,
Desantis and Safariland are my choices for carry holsters, check their websites for ideas. Better yet, go to a gun shop and try on the holsters first, to give yourself a better feel for them. I would reccomend a strong-side, thumb-break style holster; stay away from shoulder rigs, cross-draw, and small-of-the-back style holsters. Fobus, and Kydex holsters are nice and cheap, but a little large for concealed carry.
I would stay away from "tactical" lights because if you are searching with it you are essentially pointing your gun at friendlies, and potentially, other officers. The skill sets involving using a weapon-mounted light are specific and unless you are issued a light along with relevant training, they can be a hazard to yourself and others. Buy a good maglite or sure-fire or some other light and practice light techniques, be it chapman, harries, FBI, puckett, or many others.
