I personally think the SLS only holsters are ill suited for duty use.

In my opinion the Safariland ALS is the only way to go for a duty holster with active retention. I carry the 7360 for a Glock 17.

If you carry a light I would make sure to get a holster that better covers the trigger than the Safariland 6xxx series does. From what I've read the 7xxx light bearing holsters do a better job of covering the trigger. You would need to do the research though.
