Hello and Welcome to our Forum! It's always good to see new folks, maybe make new friends, learn new things. We try our best to help everyone that asks, and when we can't we try to point them to where they should be able to find their answers. And I can say with a little pride that everyone here are good people, and we have not often failed. As you can see CZ04FT has already come up with an answer that I think you will like.
I had to carry a holster like that for a few years and it always made me unhappy, I KNEW the strap was there to help protect my life as much an the keep the weapon from falling out during a chase. But I always wonder if I would fumble the snap/release some day. I like the holster and won't turn my nose up at one especially if it was a gift, and I am very tempted to actually buy one since not a lot of holsters are made for the 82. (BTW and 83 holster works just fine) And the price is great, and if you are getting it because you are now on the job, or working security then I would seriously and strongly advise you to get one of those. That retention strap can save your life with some luck and your ability to handle yourself. ALLWAYS, allways remember to protect your weapon during a fight. And that strap will help do that.
