Let me try this again. I initially replied on the wrong Crescent post, sorry.
Without measuring, the firing pins seem to protrude properly with the barrels off. Remember that the cocking rods/dogs recock the hammers when opened. With the barrels off, the cocking system is not operating and the firing pins look right, but may be restrained by the cocking rods/cams. The forend generally activates the cocking system. Using a long rod down each barrel, check the firing pin protrusion in each barrel with the forend on, and off.
