Does the frame mounted firing pin normally protrude slightly through the firing pin bushing. I have a model 22-4 and the ammo drags and binds with both moon clips and auto rim. It leaves a ring from the firing pin in the ammo that passes. These are reloads but they work fine in my 25-2. I used a lee factory crimp die and oal length of 1.250. Both fmj and lead swc tie the cyl. up. I am not the original owner. I have never tried factory ammo as I have none on hand.
Absolutely NOT. There is supposed to be a spring that holds it back in the frame. You have an unsafe condition and you should send the revolver back to S&W for immediate service.
