Tank, my apologies, but I don't think there is any such thing as a "good NYLON holster." Now, if you are looking for a good drop leg holster on a nylon rig, I would have a Kydex holster made and attached to a drop rig. The Kydex will hold your firearm much better and not destroy the finish with thousands of draws and re-holsters. There are a few custom holster makers that do this, but the one that made my wife's is Brandon of www.SharkTac.com. It's not on the web page, but he custom builds them to your satisfaction. Just drop an email at the website and tell him I sent ya - he'll take good care of you. ;-)
