The SCD and Flat Faced Glock Triggers

[spinmove_]

So I’ve got a standard SCD on both of my G19s. I’m currently running G17.3 trigger bars in both as well, but lately was thinking about giving a flat faced trigger a shot to see if it works for me or not. I know there are two variants of the SCD, one for standard pre-travel and one for reduced pre-travel. I’m ideally looking for a flat faced trigger that doesn’t have any reduced pre-travel and also maintains all internal safeties.

Which flat faced triggers do not have reduced pre-travel? How much would a standard SCD stick out with something like the Overwatch Precision triggers?

So basically even with the Apex flat faced trigger the SCD is going to stick out a bit? That sucks.

I have two gen 4 glocks 26/19 that has the non-reduced scd that have the apex drop in trigger (gen 3 trigger bar) and they work great. I also have the new scd for the 43 which has the apex trigger shoe only (trigger bar is oem) and it works fine also.

This is timely.

I have a Gen4 19 with a Tyr trigger currently installed. I'm also experimenting with AIWB, and was going to put a SCD on this pistol.

Is there a list going of aftermarket triggers that do not defeat any of the factory safety systems?

[jlw]

The SSVI Tyr trigger has only minimal pre-travel reduction and is good to go with a non-reduced pre-travel SCD on a Gen4 gun.

Cool.

Ahhh, I remember reading the post in the above link but had completely forgotten about it (probably because I hadn't, personally, considered installing another trigger until that recent 'small hands' thread). I have an Overwatch TAC on the way for testing and screwing around a bit. I'll revert back to the stock cover plate while the TAC is installed.

Tom_Jones Any idea if the Gen 5 SCD will work with the Overwatch Precision or Apex Gen 5 triggers?

I'm probably picking up a Gen 5 19 in the next few days and I'm not willing to go back to the dark ages before the SCD but have really come up like my flat triggers.

As I mentioned in the Gen5 Glock thread, Glock has effectively given us reduced pre-travel triggers in the Gen5 guns since the trigger bar vertical extension starts out essentially in contact with the firing pin block. As such, there’s no “free” pre-travel you can eliminate while simultaneously using an unmodified OEM trigger bar and maintaining the integrity of the firing pin block.

I’ve not bought/tested any Gen5 after market triggers yet, but I do have customers I trust that say that the Gen5 triggers from OWP are good to go with the Gen5 SCD. I’m relatively sure that the APEX and SSVI Gen5 triggers are too.Thanks Tom, that's what I was hoping you'd say!

Not sure why this is an issue, but blame the trigger, not the SCD.

Oh, I am. Please don’t misunderstand me, I get that the SCD was originally engineered and intended for an all OEM Glock. I’m more saying “it sucks” to the fact that even a seemingly full pre-travel trigger like the Apex trigger could make the standard SCD stick out. All I want is a flat face, that’s all.

Still might try an Apex or SSVI.

Sent from mah smertfone using tapathingyFor what it's worth, my Gen 4 works fine with a standard SCD and an Apex trigger.

I wouldn't worry about it if it works properly then. I've been using the SCD since 2011, I don't even notice it moving during shooting anymore.

The ones off the top of my head are

SSVi
Overwatch Precision
Agency arms
Apex
OC Custom

Just an unsolicited $.02 worth, but I bought in on the SCD's with the Indiegogo funding and have them on all 3 of my Glocks. Through several thousand rounds by now I too don't even notice them, and couldn't imagine owning a Glock without one.

I know I'm demonstrating my ignorance here, but what would the advantage of a flat face trigger be? I promise I'm not trolling, simply wishing to learn.

A bit old, a little long, but still a good thread from M4C.

I just got done playing with the IGFS polished, which was that dude's first choice at that time. A regular Gadget sticks way back.

Oh, and to answer the question you actually asked... I’m not familiar with all aftermarket Glock triggers, but I’d be surprised if there were any flat faced triggers that didn’t reduce pre-travel since a flat face trigger, without pre-travel reduction, would almost certainly increase trigger reach which people dislike almost as much as pre-travel. :)

I think I know what you mean, but just some pedantry: flat doesn't necessarily mean vertical at rest. I've long been curious to experiment with a OEM trigger that has had the front, horizontally radiused (stepped on the G19) surface sanded flat, provided the trigger safety could be left uncompromised.

[GRV]

I didn’t say, nor mean to imply, it did. However, I’m pretty good at being lousy at communicating what I do mean, so it’s understandable. :)

Ah, in that case, why do you feel flat implies increased trigger reach or reduced take up? Consider the thought experiment of going to town with a dremel on the front of a stock trigger shoe.

[GRV]

Geometry and experience with way too many (but certainly not all) aftermarket triggers. :)

If you feel you can make a functional, safe, and robust flat face trigger (vertical, or not, when the trigger is fully forward and at rest) for a pivoting trigger system like the Glock that neither increases trigger reach or reduces pre-travel, and that provides benefit to the user, you should. :cool:

My only interest in aftermarket triggers is to determine compatibility and suitability for use with stuff I make/sell. Anything further I say would likely not be of value to anyone who is interested in such things and would look like product bashing.

Hmm. I feel most aftermarket triggers have a number of goals and don't necessarily exhaust the space of what's possible.

Yea, I'd like to try it some day. Practically speaking it doesn't mean much to me, which is why I haven't gotten around to it, but it remains an intellectual curiosity.

Maybe this would be a conversation best continued over PM.

I got my Gen 5 SCD and Gen 5 Overwatch Precision trigger in the mail today. I had to do a bit of filing to get the SCD to sit flush, but now it looks good, is functioning correctly, and the trigger feels amazing.

Tom_Jones Have you heard of any reports of rust from other people who have filed down standard SCDs to get them to work with reduced pre travel triggers?

[dontshakepandas]

If the Gen5 OWP triggers causes the SCD to “stick out”, I’d very carefully check that the firing pin safety isn’t being (even just a little bit) disengaged when the trigger is fully forward and at rest.

The SCD is made from 17-4PH stainless steel (an alloy commonly used in marine environments) so rust/corrosion shouldn’t be a problem.

What is the best way to make sure the firing pin safety is being disengaged? I was slightly concerned with that when I installed everything, but it's passed all of the safety checks I could find to try, but I'd certainly like to be as sure as possible.

[dontshakepandas]

In the second post in the thread, I linked to another thread where I talk about the way I check that the firing pin safety isn’t being disengaged when the trigger is fully forward and at rest.

Thanks. Not sure how I missed that. Based on that thread, I think it's good.

It's about as close as it can possibly get, but the firing pin safety isn't depressed at all when the trigger is at rest. It is depressed veeeeeery slightly if I pull the trigger back to where the trigger safety makes contact with the frame, but still has quite a bit of travel left before it reaches the point where the striker can pass. Does that sound like something I should be concerned about?

Thanks again for the feedback. There is a lot of bad information on the internet, but I really value your opinion.
