himurax13 Posted August 30, 2017 Share Posted August 30, 2017 Recently, one of my shadows (Type 3 Disco, CZ Comp Hammer, old 85 Combat Trigger, 11.5# mainspring) has developed an issue. When I am dry firing in double action, the trigger does not always fully reset. It works fine in single action though. At first I thought I needed to fit the disco a little more but the single action reset is a bit further than my other Shadow and it used to work fine previously. I am a little tired right now so I figured I might be missing something simple. Any thoughts? Link to comment Share on other sites More sharing options...
SlvrDragon50 Posted August 30, 2017 Share Posted August 30, 2017 The DA and SA fit points are different. You need to file a bit more. Just a tad. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
eerw Posted August 30, 2017 Share Posted August 30, 2017 so gun used to work and doenst work now? how frequent? occasional or all the time? Link to comment Share on other sites More sharing options...
SlvrDragon50 Posted August 30, 2017 Share Posted August 30, 2017 Silly me. Stuart's question is very important. I was assuming it was a freshly fitted disco. If it's over time then it's likely a different issue. Link to comment Share on other sites More sharing options...
cheby Posted August 30, 2017 Share Posted August 30, 2017 Make sure the trigger bar lifter spring is fully in grooves of the bar. Sometimes it gets out of the alignment (During the cleaning of the gun for example) . You may even have to bend it a little. It happened to me a few times. I remember there was a thread in the past addressing this situation as well Link to comment Share on other sites More sharing options...

It has been a while since I have used this frame though, maybe like 2 years. 1 out of 10 pulls it won't reset.

There's no fitting the DA of a disco, only SA to make it reset, fit, etc. The wing is pushed back by the trigger bar, then it rides up as the trigger bar slides under and off, breaking the DA shot. Also, a weak trigger return spring or dirty gun can get you silly in DA reset. Link to comment Share on other sites More sharing options...

I replaced the trigger spring with a new one and it did not change anything. I fit my trigger bars to the disco, but I do cut an angle on the wing and maybe some other material if necessary. I just swapped the trigger and trigger bar with one of my other frames and it worked fine. Edited August 31, 2017 by himurax13 Link to comment Share on other sites More sharing options...

Pro tip - if you break the wing on the disco, you're not tuning your gun right, and your DA hammer strike will be shorter.

Tok36 Posted September 1, 2017 Share Posted September 1, 2017 I am bit lost as well. In some cases with some pistols and upgrade parts it seams unavoidable. But i may be missing something, it has been know to happen. Link to comment Share on other sites More sharing options...
mikeinctown Posted September 4, 2017 Share Posted September 4, 2017 That may be true assuming that all parts are 100% within spec. Link to comment Share on other sites More sharing options...

I rarely have to take off any additional material for the double action stroke. Edited September 4, 2017 by himurax13 Link to comment Share on other sites More sharing options...

As I'm sure you're inclined not to believe me, since you keep telling me I'm incorrect, but you want that wing at a crisp 90*. If your gun is tuned CORRECTLY, take a little material off the top part of the disco to get it to sit a little higher under the sear cage. We're only talking .008" (if that), give or take. That will give the trigger bar the clearance it needs to fall below the wing, while still keeping a crisp, deep, and solid DA stroke. Making any modification to the wing will give you an early, and short(er) stroke in DA. That's a fact. And I'd throw that instructional picture away, it isn't very good advice. Good luck.

There is no CZ disco on the market that should need to have the wing modified. You're inappropriately changing the timing. It's incorrect. If Zeus shot a lightning bolt down with a message that said mod the wing... you still shouldn't do it. The proper way is to remove a slight about of material from the top of the disco in order for it to sit higher under the sear cage. The keeps the timing the same but allows for a proper break in DA. Is a stroke breaks too soon, you modify the nose of the disco to give it more time on the bar. So, while I wish you the best in whichever method you choose, the fact remains, and will always remain - you should never break the wing on a CZ disco. Ever.

This may sound like a stupid question - but when you say top of the disco, are you referring to the red area as shown in the picture below? Or are you referring to the nose tip of the wedge?
