Tiny Screws in CGW Part #75585

[TNman]

I received part # 75585, 85C "Old Style" trigger from CGW for my CZ 75D Compact. I was able to remove the original trigger fairly easily. I am about to install the old style trigger and noticed two very tiny set screws in the package. I assume these are to adjust over travel but I cannot find any information regarding how to install the two screws or how to adjust them.

One screw is a tad longer than the other. I screwed in the shorter screw into the lower per-drilled and threaded hole but I have no idea what it is suppose to do or what I do with the other one. Hopefully someone will understand what I am trying to say and give me a tip on how to proceed. - Thanks

Does this help?

The video does kind of help but My 75 BD does not seem to have the same set up at the SP-01. The video speaks to screws around the hammer area and I thought they went into the 85C trigger face. But I could be confused.

Oh I was referencing the screw holes in the trigger, sorry I wasn't clear.

[TNman]

Me too. The trigger face has two pre-drilled threaded holes near the top of the trigger face. the very top hole I left empty. The other one, as shown in the earlier photo is where I screwed in the longer set screw. I have now also screwed in the shorter screw into the top hole on the trigger face. I guess I am now ready to just put the trigger back in the pistol and I'm done?

STOP! Your screws are in backwards.

[cntrydawwwg]

Double check all your paperwork that came with your package. CGW usually sends instructions on setting the screws.
   Yes, short screw in top, long screw in bottom. But you need to be able to get at them for adjusting.
   I'll look thru my stuff and see if I still have the paperwork.

For sure the bottom setscrew is in backwards.  You want to be able to adjust the bottom screw with a small hex key wrench when the trigger is installed.  You adjust the screw to minimize the over travel of the trigger.

I don't own a trigger with the pre travel adjustment (upper set screw) so I can't comment on that install.

I'd suggest you give cgw a call and have them walk you through the install. 

You can also just remove both and not have any trigger constraints.  One risk is if these move it could render the firearm inoperable.

Cheers,
Toby

Do you have the Reach reduction, or just the trigger?
   If just the trigger, you don't use the top screw, as that is the pre-travel screw for use with the RRK.
 Sorry, can't find my paperwork[emoji17]
    As Tdogg said, just remove both screws until you can contact CGW. Both screws go in from the face side of the trigger. You won't have to remove the trigger again to reinstall.

The overtravel screw (O.S.)needs to allow adjustment when the trigger is to the rear

The upper reset screw (R.S.). Needs to allow adj. when the trigger is forward.
These adjustments "need" a little slack in the adjustments.

O.T.:  my method,   screw in the adj screw until the trigger won't drop the hammer.  back the screw out until it will just drop the hammer.  The add a full turn or more adjustment out,  so it will reliably drop the hammer clean or dirty. Don't set it too close or "Murphy" will happen.

R.S.:for the reset adj. Screw,  adj. the screw IN until the hammer won't reset and then back it out until it just resets.  Then I add another full turn or more for insurance.
 Many adjust these screws too close and have the trigger occasionally fail to reset when released forward or fail to drop the hammer when pulled to the rear.

Just my practices

And CGW instructs to apply Locktite (Red, I think) to the screw threads to maintain their position...

Red is permanent.
Your decision.

[schmeky]

Instructions indicate:

Top screw = red loctite
Bottom screw = blue

We don't send instructions with the 75585 by itself.  We do for all the pre-packaged kits. 

[cntrydawwwg]

Thanks for clearing that up Schmeky.
   Am I correct in that the Pre travel (top) screw is only usable with the modified RRK disco?

[schmeky]

cntrydawwg,

Yes sir, you are correct.
