Default Apex Trigger Woes..

I'm trying to install an Apex flat faced trigger, but of course, I can't get the pin through the trigger to capture the trigger bar...

Apex tells me the issue is that I used a punch, and the punch mushroomed the pin. They say I should have used a vice. The pin does look a tad bit mushroomed...

I was able to get get the pin most of the way in using a vice, but it's not flush. My question is, does it even have to be, or am I good to go?

Without seeing a picture, it's hard to say. How "not flush" is it? My feeling is that it wouldn't matter. If it captures the trigger bar, then it should be ok, you could file any protruding part of the pin to be sure.

The pin does not need to be "driven" in or out, you should be able to push it out with a punch and push it back in with nothing more than finger pressure.

I use a small flat blade screwdriver going in from the left side. The screwdriver is just barely small enough to fit in the holes. Feed it through all the parts to the other side. Then take the punch and follow the screwdriver back through the other side. Finally line up the pin with the punch and push it through the left side until it's flush. By "chasing" the punch, everything stays lined up especially the trigger return spring.

I think the rear of the trigger return spring is pointing with the hook down. I'm not totally sure if that's critical, but that's what I was told so I did it.

The important thing is the pin must be fully seated on the right side of the frame or else it will eventually disengage and mess things up.

Order a new pin. Meanwhile, take a small jewelers file / stone and "fix" the end of the pin so that it fits the way it should.
p.s If you had to hit the punch hard enough to mushroom the pin, something was wrong from the start.

One thing is for sure, that pin isn't coming out during normal operation. As noted in other post on te forum, the pin was extremely tight from the get go. I was only able to finally force it in most of the way via a vice and my body weight.

I googled to see if others were having this same issues, and came across a couple of threads where the consensus was that this was normal with the aluminum trigger... From the responses I've gotten so far on this thread, I'm guessing that it's not?

Even in the YouTube tutorial I watched, the guy only used padded wrench... I agree, that something was wrong from the get go, but Apex is blaming all on using a punch...

Do you remember who you spoke to? I would be curious to know since they should be offering solutions, not blame.

If you are still having issues, please contact our customer service again and let them know you are stuck at an impasse, and that the pin won't budge. They really are here to help.
Sometimes the anodizing build up around the hole causes the pin to be difficult to move. The fit has to be somewhat tight to prevent the pin from walking out under repeated recoil, but it should go in smoothly once the hard anodized shell gives way.

Ask for Krystal, as she is the Customer Service Supervisor. The worst case scenario is that they will ask you to send the trigger and bar in, and we can remove the pin and replace the trigger.

-Randy

Default Same Issue is there a fix?

I am trying to install a flat apex on MP45 M2. Im having same problem driving pin into trigger bar. Is there a solution? Pin is stuck, Id hate top keep strinking it. Is it possible to drive it all the way thru then flip pin and try to reinsert? I started driving pin with vice but missed hole because originally pin was flush and would not latch to start pressing in. Now pin is somewhat started .03 and I cant place bar in now. I tried to punch pin backwards but nothing. Can I drive all the way thru or is it tapered?
