Recently purchased a Glock 19 gen 4. Told it was basically brand new. Has Tru glo sights, trigger job which includes after market connector 3.5lb and upgraded spring kit from zev tech. Can anyone confirm this based on these pics? Or do I need to truly dissemble it? I had a few FTF with WWB 9mm, and a u notch preban 15 rnd. Have NOT tried any other ammo or mags. Only shot around 85 rounds. Did a lot of research and found this was common in break in, but want to make sure the spring kit isn't causing the FTF. My Sig or HK never had issues with that ammo, or during their break in period.
Other than that I wish I had bought into glock earlier. Feels a bit more comfortable in my hand than other hand guns, and have Talon grips coming in the mail now. About to head out to the garage and dremel the hand guard as well.

I can see what looks like beryllium copper grease, so that tells me it's pretty new. IMHO Glocks are best with Glock parts. If you have the stock parts, put them back in.

What they said. What type of failures are you having? Weak range ammo and Gen4's don't always get along when the recoil spring is new. Especially if it's an early Gen4 with the heavier recoil spring assembly Glock replaced with the lighter one. What numbers are on the recoil spring assembly(RSA)?

I'd be wary of a "trigger job" done by some nobody. You don't really know for sure what's been done.
I'd be inclined to replace everything with factory parts and not look back. Is "FTF" supposed to mean "Failure To Feed" or "Failure To Fire"? If it's failure to feed, it could be a bad magazine (replace the whole mag) or you may not have the current recoil spring assembly. If it's failure to fire, the previous owner may have monkeyed with the striker spring. Replace it. |

If that is the factory copper grease stuff, I would thoroughly clean the pistol and reoil it with your preferred lubricant. My experience with Glocks is that this initial step will seemingly make it operate more smoothly.
The trigger job is likely not an issue, but I personally like the stock components - at least we know these are reliable. It is sorta difficult to trust someone else's trigger job. |

Your problem is the spring kit -- never put a reduced-power firing pin (striker) spring in a Glock if you want reliable ignition.
You need to install a factory firing pin spring. It will add about 1/2 pound to the trigger pull weight, but will take you back to the reliability you want/need. |

First change the ammo and mag. If it still does it, put the Glock parts back in. Lube it. Shoot a few hundred rounds to break it in, and see if it clears up.
If you want to mod the gun, add the parts back in one by one and shoot it to see if any one is causing the issues. I have stock and modified Glocks. All of them run great when lubed. I like Ghost connectors. |

I'm no expert, but I have never had a FTF in my 19 in over 10k rounds. All kinds of ammo, steel and aluminum as well. Can't tell about the trigger, cause mine is a gen3. Internals look clean though.

Looks pretty much brand new to me. I'd take the advice above and go back to factory parts. Who knows what kind of Bubba trigger job was done. Use factory mags too.
I just installed a Bill Springfield trigger on an AR and switched to another AR as my go to HD AR until I can verify the new trigger is reliable. Just FYI, as I'd want to be sure my gun is reliable before I rely on it. I'm sure it will be fine, as he does great work, but I want to verify. |

How does the finish look, does it have any evidence of the action being used around the breech/locking lugs? If it's not a stock Glock part, I'd ditch it. |

Ok...just making sure you weren't fixing to go full retard with the dremmel. I make the undercut slightly bigger also. The best vendor for Glock parts is Glock. There isn't much need for crazy aftermarket parts IMO. I use the Glock extended slide catch and Trijicon HD night sights. Short of that the Gen4s don't really need any other mods. Seriously, don't monkey with it. |

Glocks can run fine with reduced power striker springs. I run 4lb springs in my G17 and have never had a light strike with reloads or factory.
I have run a 2lb striker spring, without the extended striker, in my G35 and have not had a ftf or light strike yet. These are both competition guns and I would not run those springs for a carry gun, if I could in fact carry.

I have the Zev competition kit in my gen 4 23. With the heavier of the two striker springs. It has been perfect through a couple thousand rounds so far. And it's my work/carry gun.

Gen4 9mm Glocks have issues with ejection. (This is the same issue that was giving guys the infamous brass to face.)
I'm not sure if Glock has finally admitted to this problem. I know guys were sending their pistols back to Glock and the issues were never resolved. Some guys were chasing their tails trying to fix this. Replacing the ejector with a Gen4 .40 ejector, replacing the extractor, replacing the extractor plunger assembly. Apex finally came out with their "failure resistant extractor". I hadn't really read up on how well they work. |

Night sights are the only upgrade needed for a Glock. Once you start monkeying around with the internals is when the trouble starts.

Quote HistoryThen it's got nothing to do with striker springs. Now that he has defined what he meant by FTF, I agree. But I'd still replace the striker spring if the gun is gonna be used for SD. I would now suspect limpwristing to be the root cause of his feeding problems. |

I have had fail to fire from a light striker spring. Went back to stock and it has been flawless. Lesson learned over the years, you can replace any spring in a Glock you want except the striker spring, don't mess with that, ever. So far as feeding, use a pissed off death grip, different mag and ammo, and shoot the heck out of it. Then get back to us. |

Went out again today with 3 new types of 9mm brass. I had failures to feed with all of them. I only have one magazine so it could be the magazine. Had a friend shoot as well, he had the failures too. It is not limp wristing. Here are some pics. It was very random. Shot about 100 rounds. I should of brought my other firearms to see if they fed the ammo ok as well.
So what exactly do I need to change out?

Spring kits lighten the firing pin spring to give better trigger feel. The downside is reduced reliability and FTF problems . It is a common problem . The grease is not a definite that the gun is low mileage . I have a can of the stuff and will sometimes add it to guns I service .
