A method for making a firearm having a bi-directional trigger pull, comprising:

• providing a firearm having a receiver;
• providing a trigger disconnector having an upper portion, the upper portion having an upwardly directed hammer hook attachment, the hammer hook attachment having a length, the upper portion hammer hook attachment having a forwardly directed hammer hook with the hammer hook having a length, the ratio of the length of the hammer hook attachment to the length of the hammer hook being about 5.46;
• providing a trigger having a rearward, pulled orientation and a forward, unpulled orientation, the trigger disconnector being coupled to the trigger;
• providing a hammer having a hammer lip, the hammer lip configured to contact the trigger disconnector when the trigger is in the pulled orientation, the hammer being coupled to the firearm receiver;
• providing a fire selector having an operational portion having an external diameter, the fire selector having fire control recess therein, the fire control recess of the fire selector having a depth, the ratio of the operational portion external diameter of the fire selector to the depth of the fire control recess of the operational portion of the fire selector being about 2.2;
• and
• providing a trigger assembly pin, the trigger assembly pin operatively coupling the trigger and trigger disconnector to the firearm receiver;
• wherein the trigger causes discharge of the firearm when the trigger is moved in a pulled, rearward direction and the trigger subsequently causes another discharge of the firearm upon trigger return.
