What are your thoughts on paddle style holsters?
I'm generally not a fan. However, most of my holsters are bought for concealment purposes. If I was choosing a range/training/competition holster (or if I was LE, who seem to be the folks most interested in paddle holsters), a paddle holster may be something I'd consider.
The key feature of most OWB concealment holsters is the trailing loop, the loop aft of the trigger guard. A pancake has one, a Nelson #1 Professional (55BN) has one, and Tucker's HF1 has one. The trailing loop is what pulls the grip into the body to help concealment. Most, probably all, paddle holster lack this feature. Without the trailing loop, most holsters will allow the grip to stick out like a diving board.
I have noticed a couple of kydex paddle holsters that don't have a trailing loop, but appear to do a better job of bringing the grip in to the body than the typical paddle holster,
