yep, Freedom Arms highly suggests them. I have been using the A-Zoom brand and they are red, so also easily identifiable when checking the firearm (I still do this EVERY time even though in my head, I know that I stored it with the snap caps)I don't get to shoot at the range as much as I would like, so I do a lot of dry firing, and I can tell you for certain that it helps you acquire your sight picture faster and easier, and your trigger squeeze and form improves if you don't get sloppy while practicing
