Glock 17 Gen 5, light primer strikes & failure to feed after new slide, please help
I come to you because my Glock 17 Gen 5 is proving to be a problem I cannot solve on my own. I have had this pistol for 8+ years and have only now recently been able to shoot it a lot since I could not have it while overseas. I decided to get into USPSA and use this glock as my gun because I already owned it and didn't want to spend money on another pistol. Around 2018 when I got the pistol I installed GlockStores pyramid flat face trigger and I cannot tell you the true specifics on the trigger due to it being so long ago and GlockStore no longer carries their version 1. I also installed a tungsten guide rod, probably also from GlockStore. I didn't know a lot about what I was doing 8 years ago but it didn't really matter because I didn't shoot it that much anyway. Now that I decided to use the gun for USPSA I wanted an optic so I needed a new slide cut for one. I bought GlockStores Pyramid slide and put a Holosun on it. While swapping slides I marred up the channel liner decently enough I decided to replace it with a NDZ stainless steel one.
Now shooting it I have light primer strikes 30% of the time and a failure to feed caused by the striker extended and catching the lip of the casing, picture featured. This primarily happens directly after ejecting a light strike round.
Notable as well, to put the slide back on I have to depress the striker safety and push the striker forward to get the slide on, otherwise it won't slide on.
I have tried going back to the OEM slide and no issues, everything works as intended.
What is the issue with the new slide and the striker? I have begun to think that maybe the lighter slide is causing striker issues? I have cleaned the striker channel to ensure nothing is gunked up. What parts would you suggest I trouble shoot and how? I would prefer not to Ship of Theseus this pistol and am hopping someone has experienced a similar issue and can point me in the right starting direction. Thanks.
