| Need some help here. I inherited my dad's Glock 33. I took it out yesterday to put some rounds through it had the first round was a light primer strike. The second round fired. The third round and fourth round double fired. I immediately unloaded in a safe manner and put the pistol away. I know the trigger and recoil are aftermarket. I want to go back with factory. Where can I find these? Not sure what else is aftermarket. There are so many parts and different numbers. Thanks. |

If you don't know what is stock and what is not it might be best to take everything to stock check out
Trigger and trigger bar Connector Trigger housing with ejector Trigger spring Recoil spring If you do replace everything and still get light primer strikes you'll want to try changing out the striker spring |

I'd put a factory trigger bar, connector, and trigger spring in the gun. Also take the firing pin safety and firing pin safety spring out of the slide and make sure the firing pin safety spring is fully seated into the firing pin safety, the spring should 'click' into the safety. You should also get a new firing pin spring, and if the firing pin looks aftermarket you may want to replace it as well or at least use an extra strength firing pin spring. A new firing pin can be quite expensive. If the firing pin is aftermarket it would probably work with a factory firing pin spring, but people often put lighter firing pin springs in to reduce trigger pull weight and that can cause light strikes. If after you replace all of those parts you still get non-semi-automatic fire, you should replace the firing pin because someone likely polished it and removed too much material from it.
(all numbers are Glock's manufacturer part numbers) 1. New trigger bar, either part #357 or #2303(357 has smooth trigger pad, 2303 has serrated) 2. New factory trigger spring, part #350 3. New factory connector, either standard #343, minus #721, or "dot" #7965 4. New firing pin spring part #63 Some other good retailers are LoneWolfDist.com and glockparts.com Also I'd detail strip and clean, then reassemble. You can use rubbing alcohol, Hoppe's Elite Cleaner, or M-Pro7. You can oil inside the slide internals if you want to, just make sure to wipe them absolutely dry afterward because the slightest amount of excess oil in the slide internals will collect excess residue and cause malfunctions. The only thing you probably don't need to take out and reinstall are the magazine catch, magazine catch spring, firing pin channel liner, and sights.

I learned from the Update Manual and 2009 Manual. The 2009 Manual has a few pages missing, but that info can be found in the Update Manual as well. (the author of that site specifically requested not to hotlink to his page) http://stevespages.com/page7b.htm Here's an easy way to disassemble and reassemble the firing pin assembly: http://glocktalk.com/forums/showpost.php?p=17097446&postcount=3 Slide Stop change/install: http://www.youtube.com/watch?v=NQbYqWBLa9w (^^^DO NOT use a mallet to force the pins, move the slide stop forward and backward, up and down, until the trigger pin slides relatively freely through) Correct slide stop spring position: http://glocktalk.com/forums/showpost.php?p=15738529&postcount=3 Magazine disassembly: http://www.youtube.com/watch?v=HpRquLIpolc NOTE: Older followers attach to the spring by putting the end of the magazine spring coil through a plastic loop on the bottom of the follower(like the follower you see in the above video). The newest followers don't have that loop, they simply have two plastic ledges to hold the spring in place, so pull the spring out of the follower until it "pops" out of the follower and push the spring into the bottom of the follower until the spring "pops" into place in the bottom of the follower. Here's a video showing how to change the magazine catch: http://www.youtube.com/watch?v=oE_AM6GWVsQ (removing all of those other parts is not necessary, I guess he does it just to get them out of the way) I'd wrap the screwdriver lightly in masking tape or thin electrical tape so it doesn't scratch any plastic. Better yet, use something with a rounded end like a curved dental pick. If you need to change the mag catch spring, you can use a pair of needlenose pliers to pull the spring out and push the new one in, I'd wrap the pliers lightly in masking tape as well. There isn't a very good video for removing the slide lock and slide lock spring. You can use the Glock tool(3/32 inch punch) to depress the spring while you remove the slide lock, but removing the spring ideally you need something thinner like a 1/16 inch punch or even thinner. To remove the slide lock you push the spring down closest to the slide lock, while holding the spring down you tilt the frame to the side and wiggle the slide lock around until it falls out. Then you put the thin punch under the slide lock spring from the rear of the frame, move the tip of the punch up to where the spring goes into the frame, and gently incrementally work the spring upward. Take note of which way the spring goes back in. When putting the slide lock back in, it should be positioned like this: http://tinypic.com/r/2zxw6s1/7 |
