When you know your'e dealing with experts. I did wonder how the Stirling quieted the action. Being an open bolt, the mass is critical and of course you would get some gas escaping on ejection. On the revolver side, SOE did produce a padded sort of glove that a revolver would fit into, one shot only and quite hairy to use I'd have thought. Makes me laugh when you see the 'baddy' in a film shove the barrel against a pillow and all you here is 'phut'.
