I recently had a holster made with snap loops. My first one.
I can't tell you how convenient it is to have the ability to remove it on a whim without having to un-belt. And it's just as easy to re-attach, too.
At first, my biggest concern was that the extra thick snap loops were going to create a problem with concealing [printing] the rig, but that wasn't the case. The holster also keeps the weapon tight to the body.
I'm very happy with mine. It was made by TT Gunleather.
Here's a few photos....
