How do you take the top slide off a HFC Glock 17 HA-117?

Answer 1

Remove the magazine and make sure the gun is empty. Actually pull the slide back, look in the chamber and make SURE the gun is empty. You need to have an uncocked gun to do this, so after pointing the gun in a safe direction, pull the trigger. Now hold the gun in one hand in such a way that you can retract the slide a bit (less than 1/2 inch) and hold it in that position with just one hand. I put my thumb on the back of the grip in the normal firing postion, then wrap my fingers over the top of the slide. Then with just a little squeeze, I can pull the slide back the necessary amount. Then with your other hand, pull down on both the small levers near the front of the slide on both sides of the gun. That unlocks the slide and allows you to push the slide forward off the front of the frame.
