So i think i killed my glock....

[Kohaku2416]

Not lugers but yeah to all the gun people out there. i bought a new york trigger and was trying to install it in my Glock model 22. well i got the spring in and reassembled my gun. However.... i wasn't paying attention and didn't realize i hadn't put the pin back in the grip of the gun that holds the trigger mechanism in place so when i put the gun back together and tried to pull the trigger it wouldn't click, it just went back. so when i tried to field strip the gun. it wouldn't let the slide come off the frame, it only goes forward about an inch forward... so then i panicked and removed the other two pins in the frame and that still wouldn't let the gun's slide come off. so when i put the two pins i did have back in the frame the slide now locks back when i pull it back, even without the mag inserted... i have no clue what ive done to screw my gun up but i am freaking out pretty bad.... idk whats going on or why the slide is locking back when nothing is in the gun. o.O and also i can't find that third pin.... so i can't even get the trigger block or whatever to stay locked in place so i can't even get the gun to even strip. Can anyone help me out or tell me whats going on or what ive done to screw up my gun....
