Glock Fail to Fire

[Counselor1977]

I bought a used glock 20. I also reload and buy professionally reloaded rounds (Georgia Arms, Precision, etc). When I started firing this used Glock, I notice that I would have a few fail to fire. I examized the non-fired round and noticed that the primer was struck but there was only a small dimple in the primer. I thought maybe the firing pin spring needed to be replace, so I replaced it. However, the problem still exists. I am wondering if maybe I need to replace the firing pin itself. I do not know how many rounds the firearm had through it before I bought it. I was told it was a police trade-in, so I am figuring quite a few. If any one can shed some light on my problem orcan direct me to a gunsmith that could examine and address the problem, I would greatly appreciate it. I am out of Lafayette, but have no problems traveling to Indy on the weekend to have the firearm serviced. Any open Sundays?

I know the rounds aren't the problem, because when I had some failed to fire (even with the primer strike)rounds , I loaded the rounds in a newer Glock 20, and the rounds fired.

Thanks in advance.

Bradis on the southwest side of indy has some excellent glock guys, and they are open on sundays.


I would also check / replace the recoil spring. They are cheap and it may fix your problem.

An FTF may be from a weak firing pin spring, or possibly a broken firing pin. As a suggestion, replace both.

Remove the slide from the frame. Depress the firing pin block plunger and shake the slide back and forth to see if the firing pin is moving freely, you should hear it bouncing back and forth. If it isn't you have enough gunk in the firing pin channel to cause an issue and it needs to be completely disassembled and cleaned out.

And then don't over oil once you get it cleaned out.

If the above mentioned doesn't work or you still find yourself in need of a gunsmith let me know, I can get you the number to one that does alot of work for indy area gunshops.

I thought glocks weren't happy with reloads?

Just a side note, I have acquired alot of used guns over the years and always give them a complete cleaning before attempting to fire them. I check for crack and bent items and I check for the overall function of the gun. To take a dirty gun that has a questionable past to the range and expect it to perform- well good luck with that.

Counselor1977 brought his gun by the shop yesterday and I took a look at it. Upon detail stripping the slide, I could not find any obvious defects on the firing pin itself, though it was the older version. I cleaned the firing pin channel out; got rid of some brass shavings and grease residue. No issue with the channel liner that I could see. The firing pin spring was found to be 1/8" to 1/4" shorter than a new OEM spring; replaced it. Also replaced the firing pin with a current production version, per customer request. Instructed him to re-lube sparingly, test-fire, and report back. We'll see what happens!

Yep, GLOCKs don't need much oil at all. Just a few drops.

When you oil your glock, on the slide, do you oil both sides? For example, on the picture above on the slide, it shows to oil the right side. Do you oil the left side too?
