How to fit a Type 3 (T3) Disconnector (Disco)

[TJART]

With all the talk lately, figured I'd make a quick and crude video for reference.

With a full polish job, hammer, and 8.5# you can get close to...

Great Stuff

Nice videos. Thank you for taking the time.

One thing has me a but puzzled. I have been of the understanding that during the DA cycle the trigger bar pushes on the front of the wing of the disconector. The trigger bar is then guided down by the notches in the slide and slips off the disconector wing. I was unaware that the inside radius of the disconector hook could effect the DA.

This animation coincides with my understanding. What am i missing?

Excellent work!

Tok, the disco rotates around the trigger bar as the DA shot breaks, if the inside corner is square the pull weight stacks up as it binds on the trigger bar.

Interesting, thank you for the clarification. I was unaware the the inside of the dico hook made contact with the trigger bar during the DA cycle.

Excellent work!

Thanks, brotha. I think the polished strut you did made a significant difference, as well.

I just installed two of them yesterday. One required no fitting at all. The other required a little bit to get it to reset in SA.

Awesome, good work!

And this is why I always, always recommend people try and drop the T3 in FIRST, before removing material. The variation in fit tolerance is so vast, gun to gun.

I've got 3k on one of my Shadows since installing a T3 a couple weeks ago. This T3 didn't require any fitting to get the gun to reset and function properly.

However, I've noticed that the hammer is following occasionally when it auto-forwards from slide lock. It isn't like hammer follow that I've experienced before. When my SA hammer hooks were rounded off, the hammer would follow down to half cock.

In this current scenario, the hammer is following all the way down but luckily it's not firing off a round after it auto forwards. Would not having enough material removed from the T3 disco cause this or is there something else going on?

Easy fix.

Get a file and increase the self on the SA hooks of the hammer.

Edit for pics;

More of a hook at angles 1 & 4

SA hooks and sear look fine. What's weird is that it's not following to half cock.

No, they're not. Look at the pics I added. You need to increase the shelf area on the SA hooks.

Suit yourself, I'm just telling you what will fox your problem. Good luck.

I've done that fix before on my other Shadow. It's not the issue.

It is, but keep chasing other remedies and post what fixes.

Lol, okay.

[d_striker]

I took a closer look at the gun. For some reason, the sear is barely clearing the SA hooks with the T3 disco in this gun. My other gun with T3 has plenty of clearance. I run overtravel screws completely backed out on both guns.

I put the pre b disco back in and sear clears the hooks quite a bit more. I believe there is some sort of timing issue with this disco.

[d_striker]

I spoke with David at CGW about this. He said to take more off the disco. After taking more off and 800 rounds later, hammer hasn't followed once.

All you did was change the angle of the hammer/sear interaction by removing more material. And in the process, probably increased pretravel, which is the opposite of what a t3 is designed for. The PROPER fix, is to file the hooks on the hammer.

But clearly you know more than me.

I'm not claiming to know more than anyone. Unlike some people, I try not to act like a pompous douche bag on here.

Well, let's clarify; I'm not disagreeing with David. What he told the other gentleman was the 'easiest' fix, not likely to result in irreversible hammer damage.

Edit: Let's also clarify design, etc. (since you brought it up). CGW sources hammers from CZC. The CZC comp hammer was not designed to work with a T3 without modification (for the most part, every gun is different). Pretty much every T3 I've fit with a comp hammer, needed some hammer hook fitting. I wasn't trying to be a douche, but I told him the CORRECT modification to remedy his problem. Understandable, because like I said above, David told him the EASIEST fix for a DIY'er, least likely to not result in hammer damage.

I've spoken to David about the T3 drop-in-ability and profiles. So don't think I'm trying to throw shade his way, as we've talked numerous times about it. So if you took my comment to heart, understand that I was trying to help you fix a HAMMER issue, not a T3 issue.

Thanks,

This was a much more informative and less douchey explanation.
