If you haven't removed the trigger guard when you pull the barrel, the trigger guard spring will remove itself, as it rests up against the bottom of the barrel. You might not find it again when it launches into the stratosphere. The only way to get that spring back in there is to remove the trigger guard and put the spring in after the barrel is installed.
