until you feel that it's light enough, if you loose the second stage go back 'til you find it again. Here is a link to a great site on the 54(same action as 48)with good trigger info;

Be patient, it takes a few seconds to load because of all the great pics/info. The trigger help starts about halfway down the page. IMO, a very helpful page. HTH,
