Cajun upgrade P-01 issues

[Crazy8]

I recently installed a Cajun omega kit on my P-01. The trigger is amazing, but I notice light primer strikes on certain brands of ammo (Magtech, all Turkish ammo). I also have light strikes using these ammo on other guns, but the P-01 never had a problem until I installed the Cajun kit.

I’m wondering if other people are having this issue? It’s not really a big deal at the range since I can just pull the trigger again for a second strike. Haven’t tried it on defensive ammo yet, and this is what concerns me. Reduced reliability for a better trigger, is it an acceptable trade off?

Edit: opps, this belongs in the CGW thread

Did you install the blue hammer spring or the black?  The blue should set off all primers.  The black will not.

I have never had any kind of light primer strikes on any brands of ammo on any of my CZ's, P-01 omega, CZ-75B omega, SP-01, PCR. However I just bought a fairly new, almost unused P-01 steel frame version and had these issues, I believe the issue is the firing pin retaining pin failure, from the previous owner dry firing the gun. I dropped it off to a gunsmith. We will see.

The blue SHOULD ignite all primers but I had the same issue with light strikes using the blue spring in a PCR and a 75B compact I recently installed the kits in. I installed the gold #15 lb spring in both those guns and the issue disappeared completely. I swapped all the blue springs out for the gold springs at that point simply so all my CZ's have pretty much the same trigger feel.
I think it's likely that some of the recently made blue springs may be weak.

I haven't had any issues with the blue springs. I purposely buy several random ammo brands for testing when I get a new gun or make modifications.

My kit only came with 1 hammer spring, which is the blue.

I had issues with the blue sear spring, so I switched to the natural. The blue sear spring made the trigger pull really weird, the DA pull had 2 distinct walls. The SA pull was even worse. I pull the trigger to the wall and it wouldn’t fire unless I pull it back even harder. Must’ve been a 15lb pull to get SA to fire. This shouldn’t have anything to do with the light strikes, but just mentioning it in case it does.

Call CGW. They are real good about walking you through trouble shooting.

Emailed CGW, they said the blue spring occasionally causes light strikes, and recommended the gold spring. It will increase DA trigger weight, not sure by how much, but not a big deal if it increases reliability.

Try Turkish ammo, like Turan or BPS. They tend to have hard primers and even cause light strikes in my 1911.

Anyone know if cz custom’s springs are good quality compared to cgw? Their springs are like half the price and they have some other parts I need. Also, is there a big difference between the 14lb and 15lb spring in terms of DA pull and avoiding light strikes?

My gunsmith just replaced my hammer main spring with a wolf 18 lb spring on my P-01 steel version and I can hardly tell a difference with my snap cap. I will take it to the range in the AM and see if that fixed my light primer strikes.

Do you also have the extended fire pin? The general consensus is that it will help against light strikes when using lower powered hammer springs.

At the range today, my P-01 steel version shot great! No issues at all! My Lyman trigger pull gauge indicates a 8.5 lb dbl action pull and a 4.5lb single action pull. Apparently the previous owner had installed a CGW #HS-12000, 11.5lb black spring, which was measuring a 6lb DBL and a 3.5 single action pull. Not that much of a trade off or perceived difference for the now reliable gun!

Nice, 8.5 is not bad.

I replaced my hammer spring with a 15lb today. DA pull went from 7-7.5lb to around 8-8.5lb. Depends on where I measure the trigger, it’s hard to get exactly on the bottom of the trigger so I usually measure 1/4” from the bottom. SA has no change, 3-3.25lb if measured from the bottom of the trigger, around 3.75-4lb if measured 1/4” from the bottom.

Gonna go shoot it today to see if light strikes are fixed.

I position the gauge in the middle of the radius of the trigger, like where ones finger pull would be, otherwise the reading will be way off.
