Tip for Removing Sear Bar That is Stuck in Trigger Pivot Hole

High Standard pistols that have been stored for a long time may have dried oil residue and/or form some corrosion in the top hole of the trigger where the sear bar pin goes in.  This can make the trigger action very sluggish or even not be able to move the sear bar much at all.  Applying penetrating oil (i.e., Kroil) in the area may help free the pin so that the sear bar can be removed.  However, sometimes the sear bar needs some help in getting it apart.  The difficulty is that there is not much space between the sear bar and the frame to get a tool under the sear bar to assist in prying it out of the trigger.  One way to do this is to use dental floss under the sear bar as close to the pivot pin as possible and pull up on the sear bar with the floss.  The trigger can be moved back and forth while doing this to help free the pin from the hole in the trigger.  Once removed, the corrosion can be cleaned off the pin and trigger hole, the pin lubricated, and reassembled in the gun.  This should allow the pivot point to work easily.  The trick is to get the floss around the sear bar.  Start at the sear end of the bar, pry up the sear bar just enough to get the floss around the end of the bar.  Work it toward the pin end.  There is a pin boss in the frame where the sear bar has an opening that goes around the boss.  The floss will have to be pulled up over the boss to allow it to be pulled the rest of the way towards the pin end.  When the floss is as close to the pin as possible, pull the floss upwards while wiggling the trigger.  This should allow the pin to come out of the trigger hole.

  1. What a great idea. Even if it's not really "gummed in" sometimes they just don't want to come out, either. This makes it easy! Great pictures, too!

  2. Great idea. Unfortunately my model 106 has been sitting for more than 30 years. I think that the pin that it is peened to sear is loose. Cosequently, the pin doesn't rotate in the trigger.
