This takes a little extra detail, as you will need to wiggle or move the slide stop lever to the front and rear of the receiver while you are pushing on the trigger pin with the armorer's tool from left to right as shown in the following picture. The second step is to remove the trigger pin. IMPORTANT NOTE! THIS PIN WILL BE THE FIRST TO REINSTALL IN THE PISTOL! FIRST OUT FIRST IN! The pin can be removed in either direction.

The first step in disassembling the receiver is to remove the locking block pin (in the three pin models). The last parts of the slide that you will remove will be the Extractor (you will need to push down on the firing pin safety to allow the extractor to drop out) IF THE PISTOL IS RELATIVELY NEW OR HAS NEVER BEEN TAKEN APART, YOU MAY USE A SMALL SCREWDRIVER TO GET THE SLIDE COVER PLATE STARTED AND THEN SLIDE THE PLATE OFF. THIS REMOVES THE SPACER SLEEVE’S LOCKED POSITION ON THE SLIDE COVER PLATE AND ALLOWS YOU TO PUSH THE SLIDE COVER PLATE OFF WITH YOUR THUMB. REMOVE THE SLIDE COVER PLATE BY USING THE GLOCK ARMORER'S TOOL TO PUSH DOWN ON THE FIRING PIN SPACER SLEEVE. YOU NOW HAVE THE PISTOL IN THE FIELD STRIPPED CONDITION. REMOVE THE SLIDE AND TAKE THE RECOIL SPRING ASSEMBLY OUT. BE CAREFUL TO NOT LET THE SLIDE FALL OFF ONTO A HARD SURFACE, AS IT COULD DAMAGE THE GUIDE RING. (IF YOU HAVE A NEW YORK TRIGGER YOU WILL NEED TO PULL THE TRIGGER AGAIN AT THIS POINT).

PULL DOWN ON THE SLIDE LOCK WHILE RELEASING THE SLIDE FORWARD. PULL BACK APPROXIMATELY ¼ INCH.PULL DOWN ON THE SLIDE LOCK BY GRASPING IT ON BOTH SIDES WITH YOUR THUMB AND FINGER. THEN GRASP THE PISTOL WITH YOUR THUMB UNDER THE SLIDE AND YOUR FINGERS OVER THE TOP OF THE REAR PART OF THE SLIDE. RELEASE THE SLIDE AND POINT THE PISTOL IN A SAFE DIRECTION.

BE SURE THERE IS NOT A ROUND IN THE CHAMBER BY VISUAL AND PHYSICAL INSPECTION.
