My personal favorite is the Safariland 3004 for general use. If I'm going to get wet, I like the BHI Airborne for its extra retention strap, mag pouch, versatility in positioning it, and the fact it's available in both OD and black. They have a new retention feature in the holster now that make them even better (I've got an old one).
With any of the majors (Safariland, BHI, Eagle, LBT) you can't go wrong.
