I think the Safariland QLS is awesome. With the exception of discovering the Glock pistol almost 21 years ago, I think the QLS is probably the best find I've ever discovered in my LE career.
Now I must warn you, the QLS system puts the holster a little bit outward from the body, so concealment with the QLS in service is challenging. If you are super skinny, it's gonna look kinda silly and print like crazy. If you are fat like me, not so much. I can pull off concealing a full size Glock 22 with the ALS holster on the paddle with the QLS installed with just an open button up shirt over it.
I fell in love with the system when I learned I can take the holster off my duty rig and put it on a paddle for maybe an off-duty application or on a 1.75" belt loop for range duty.
With the QLS system in place, my manual of arms never changes because I am using the same holster with the same ALS retention no matter what attachment I choose.
good to know, if I was using one it would not be for concealed carry. that would be raven or comp-tac
While the Raven's dont have an "active" retention the fit is tight enough that the firearm "clicks" in. Depends if the user is looking for something active because active retention is dictated by management or if active retention is just desired for great retention. I can full sprint and maneuver in a raven and the handgun never even hints at coming out. I dont own one, but will soon after recently trying one out.
active retention is really for those who are concerned about having their gun taken from them...LEOs would be a group that worry about that.
