light primer strikes

[jkgts1]

Okay ladies and gents I have a CZ 75 SP01. I have a trigger upgrade with a Cajun gunworks kit. So, I have noticed once in a long while I will get light primer strikes and the round will not fire. I pop the round back in the mag and it always fires the second time. This has happened with reloads and factory ammo. So, my thinking is that its because I messed with the gun changing this and that, and it might be.
This past weekend I noticed something very interesting. I had 2 friends shoot my CZ and they were getting the light primer strikes 3-5 times in one ten round magazine. I have never had that many even on one range trip. Both friends had the same problem, and we were all shooting the same ammo. I would take the gun back and shoot 10 straight no issues, hand it back to them and light primer strike no boom.
So, I was watching them shoot and noticed they were both very shaky when shooting. They don't shoot as much as I do so I have more time behind guns in general. Anyway, has anyone else ever seen this happen? I've heard of limp wristing and thought that usually resulted in failures to chamber a new round, but not resulting in a light primer strikes. Or are they anticipating so much that its causing light strikes? Not even sure if that is physically possible. Or my gun only like me to handle it haha jk.

Hammer spring is probably too light?

Possible, hard part is that I really don't remember if I changed it with the Cajun kit, Its been years and I don't remember what kit I put in haha

It might also be a dirty hammer spring.

Limp wristing the gun?

[eaglemike]

Sear dragging on the hammer? Tired/light hammer spring? Crud buildup slowing things down?

Contact CGW...they have excellent customer service. If you installed a CGW pro kit, you have to install included extended firing pin

Light primer strikes?

"I have a trigger upgrade with Cajun gunworks kit."

Hmmm...what could it be.

The problem might not be the trigger, especially if you are shooting reloads. Could be high primers that are not fully seated when the primer is not fully seated. High primer ammo usually fire the second time after the primer is pushed in on the first firing pin strike. I have even found high primers on factory manufactured ammo.

Correct I’m sure it’s because I changed the stuff on the trigger. And I get the reloads might be a problem. But to have that many failures in 1 magazine, that has to be a shooter thing. Like I said I took the gun back 2-3 times, shot whole mag no issue. Had my friends shoot and failures every time. It was just something I noticed, but wasn’t sure if that could happen due to shooting form.

I just cant imagine how shooter 'form' would cause that kind of issue. cycle/eject of course... but how can you possibly interfere with the hammer driving the firing pin forward because of bad form... makes no sense.

Besides what the others said.... I would strip the slide and clean the firing pin/channel to make sure there's no buildup in it slowing down the pin.

I showed a friend of mine who had these kind of issues on a cheap gun with light strikes.... drop a wooden pencil down the barrel with the eraser sitting on the firing pin. Point gun straight up and pull the trigger. Note how high the pencil was pushed up. I showed him that with his problem gun, which pushed the pencil about 1 foot up... and a 1911 which shot the pencil up about 2 feet- He clearly saw there is a problem with the main spring/firing pin/pin channel- something on his gun because how weak it drove the pencil.

What kind of primers are you using in your reloads? I switched from CCI to the softer Federal Match SSP and a similar issue with my tuned CZ's went away.

Bad form possibly preventing the gun from returning fully into battery? First hammer drop finishes closing the action, then the restrike ignites the round. Maybe the gun got a little too dirty or maybe time for a new recoil spring.

CZs also have notoriously short chambers and throats. Have you ever had issues ejecting an unfired round?
