This might be a dumb question concerning a 1914 vintage Win. 1894 that I recently received. Required complete disassembly for much cleaning of the action and barrel. Got it all cleaned up, lubed & reassembled. It was then that I first noted the considerable amount of free movement in the trigger (after installing the hammer). Like a two-stage trigger without any spring tension in the "first stage." Thought maybe there was something wrong at first but after checking others of similar age, they were just like mine. Just curious as to the reason or purpose, if any, for this. Anyone fill me in?
