Need help assembling a custom Glock

[Armed Citizen]

Hey folks, not sure what I'm doing wrong but I'm trying to assemble a Glock 17 that I'm piecing together. The upper and upper parts are from Zaffiri Precision, the lower parts are from a couple companies. I put everything together in the upper and lower and when I go to attach the slide to the frame, it won't go into battery after racking the slide. The only way I can get it back apart is to remove the firing pin so it leads me to believe something is out of spec or assembled wrong on the firing pin or trigger assembly. But I compare it to my factory Glocks and I don't see anything out of place. Also thought maybe the firing pin sleeve wasn't all the way it so I tapped it pretty hard again using the sleeve tool and it seems to be all the way in. Has anyone else had this issue? Or know what I did wrong? Any help is greatly appreciated!

If you have a factory G17, try parts swapping. Do it on part at a time.

Start out with the whole slide if you can.

Make sure you have the proper locking block.

Make sure the drop safety spring is in properly. Also, make sure the safety retracts all the way flush with ceiling of the slide.

unfortunately I only have a G19 and g34 (both gen 5 vs. this gen3)

What's the front locking block area look like? It's fuzzy in the pictures above. Other question after seeing the plate... does the striker plunger freely move up and down? I'm wondering if the striker is interacting with the plunger in a way that's blocking its travel.

Are all the necessary parts lubed? Dry Glocks do not function well at all.

Make sure you have the slide lock facing in the correct direction, with the grooved top edge facing rearward.

Thank you for the suggestions! I kept fiddling with it and figured out it's not the trigger that's hanging up, it's the back plate on the end of the trigger assembly. I was able to sand it down a bit and now it will fit together although tight. Trigger is also very heavy. Guess that's what I get for cheaping out and getting $40 lower parts kit. If anyone knows of a good replacement drop in let me know. Considering this one now.

Probably should have tried a different rear plate lol, but anyhoo, depending on what you are expecting out of your trigger I've had good luck with Orange County triggers. You can get them as fancy or plain as you want. Also, while you're at it, if you haven't already, replace the gen 3 ejector with a gen 4-5 (#30274). You won't be sorry.

Do you own a Glock inspection rear plate? If you are replacing trigger bars in Glocks, you really need one.

I second occustomtriggers.com. They also have an ebay store. Ships fast and their OEM parts prices are cheaper than most sellers.

OEM trigger bar + OEM trigger housing + Johnny glock (Ranger Proof) VEX F3 trigger works really well for me! Does not change the factory trigger pull weight but gets rid of the long(ish) take up.
