They're floating pins in both cases (my pic shows them in fired position, after taking the guns apart. I drop the hammers on dummies before storing them in the safe). About gas escape control, my double rifle has 2 hollow screws on the right side of the reveiver. They're connected to the firing pin channels to divert gas away from the shooter'd face, in case of a ruptured primer or case. These gas-screws don't deface the looks of the rifle as they're covered up in the engraving and about invisible.
