My 1st SP01 trigger job questions
« on: September 05, 2017, 07:52:49 PM »
I just finished a trigger job on my sp01 I'm planning to play in CO. I pretty much "Cajunized" mine minus the combat trigger.
 
-Sometimes my hammer will not fall whem I pull the trigger in DA, especially when I pull slowly and deliberatly. Why is that?
 
-When I cock the hammer for SA, pull the trigger and rack the slide, it has a loud and very tacticle reset. And this reset distance is what I would expect from a fpb cz. But waaay before that, there is a very faint reset that I could pull the trigger with. This very short reset is what I see in Shadow CZ's which are very short. And there is no take up on this faint reset, I'm at the wall aready and then it drops the hammer. I'm dumbfounded and thinking about safety too.
 
-Lastly, more on learning, why did I have fit the sear to the safety when I used the original sear that came with the gun? I was lazy to take out the sear from its cage so I just worked on the safety and it worked. I did have take a good chunk from the safety to engage the sear.

Here' the vid on the DA pull


And here's for the reset


Thank you. Aside from these, the trigger is amaizing; about 7lb on DA and 2lbs on SA. If that uber short reset is okay and safe, I'll take it!

Looking good!
Make sure the trigger bar spring is riding in the grooves on the bottom of the trigger bar and the bar is being lifted properly.
Make sure the safety arm has proper clearance & not too tight.

Call CGW tomorrow, they'll tell you how to fix it for sure. On the DA pull, check that the TB spring is riding in the groove and has the right amount of up pressure. If that's good, slight fitting of the DA wing on the disco may be required. But like I said, check with Cajun first.

Yeap, looks like both situation are related to a trigger bar issue. Is the connector riding the trigger bar correctly, if it's possible to ride it incorrectly?

I got a chance to observe the gun.
 
I have an ever so lighlty play on the sear cage towards the back (closest to the hammer). If I put a constant downward pressure on the back of the cage, DA drops the hammer all the time.
 
On the rouge uber short reset, I observed that the sear will drop but the fpb will not lift. If the push forward to the loud and tactile reset, both sear and fpb will move. Why is there a rouge reset though were it will drop the sear but wouldnt lift the fpb lifter?

Its seems that the trigger bar lifter spring is in the groove. Ill try to call Cajun tommorow.

Make sure the safety arm has enough clearance + a very little more extra.clearance.....not tight.
Check that the trigger bar spring lifts the trigger bar to the right height.
