Glock 19 Gen 4 with many new drop-in mods.

I recently purchased another Glock 19 Gen 4 to fit the role as my concealed carry weapon. I switch back between Glock, SIG Sauer, and Heckler and Koch. I'm a huge fan of DA/SA. However, I cannot ignore the many benefits of a Glock striker fired 'safe-action' pistol. I recently even took my Glock kayaking with me and it wasn't affected by the salt water. I have a very, very, outdoorsy and active lifestyle. It's a nice change of pace to not have to worry so much about my concealed carry weapon. Now, onto the review of the following modifications:

  • Agency Arms Trigger
  • S3F Solutions - Threaded and Fluted Barrel
  • Glock Factory Minus Conncetor
  • AmeriGlo I-Dot Pros



Took my Glock 19 Gen 4 w/ S3F Solutions Barrel, AmeriGlo I-Dot Pros, and Agency Arms Trigger w/ minus connector out yesterday to run some rounds through it to test for function and some accuracy. There we zero malfunctions in only 200 rounds of 115gr Magtech FMJs.


The barrel, just a thread barrel that looks pretty. Didn't notice any more or less "accuracy" and that's not why I bought it anyways. So since I didn't shoot it suppressed. - PASS

The sights, they're great. 90 degree cut for one handed manipulations. Nice and fast acquisition with one bright dot up front and one dot behind it. Very, very, easy to see. However, my "hold" has changed with these sights and I didn't have enough time to find the sweet spot. It shoots fast and I see them fast. Which is a huge plus. Accurate at that distance, which is granted. 5, 7, 10 yard. GTG. I'd like to tighten the groupings up a bit more as I did with the stock sights that I had down to a golf ball. That'll come with time, once again. - PASS



The trigger, also an amazing upgrade. The trigger is flat and there is zero take-up whatsoever. You're automatically at the wall. Somewhat like a 1911, which is one of my favorite, if not my most favorite trigger in the world. It isn't ultra light, as all springs are factory and I've always been a little iffy about lightening my trigger too much. I didn't expect it to be the weight it is now even with the minus connector, I expected lighter. So I'm glad it's where it is. The trigger is great, very accurate. And really, I mean really crisp. Just need a little more time to be 99% confident with it as I was / am with my other guns. - PASS

So, this is has been my review. I'll try to attach some pics as well for you guys to see. I also have a video I would love to attach of me doing a triple tap from the hip and one to the head in about 2 seconds, with the stock setup. I'll try to work on that.

Hope you enjoyed!

Twinsies. Been looking for an excuse to post the pic, anyways.

- Glock 19 BFG
- GlockKraft flat-faced trigger w/ Robar NP3 plating on the trigger bar & OEM "-" connector
- Heinie LEDGE sights with QWIK notch
- Tango Down/Vickers slide stop & mag catch
- Alpha Wolf threaded barrel

I'm quite pleased with the set up. The trigger is really nice. It's almost as good as my Sig P320's. Good stuff.

Sweet looking piece..

Do you know the mechanics of the trigger? The " take up" in a standard Glock trigger is what cocks the striker. Without that take up, how does the striker get cocked?

I grew up on 1911 triggers. Used one on duty, used one to teach for a lotta years. My G19 trigger is OK, but a 1911 it ain't:(
 
I love me a good 1911 trigger, but don't want to mod my EDC. CLEARLY, I need another G19 so that I can do fun stuff like this on it.

Good review!
 
Question: why buy a threaded barrel if you don't intend to use it suppressed?
Click to expand...

I do intend to shoot it suppressed at some point, but:

a) I like the aesthetics of the threaded barrel
b) it provides about .5" more barrel length without the goofy looks of an extended barrel, and
c) traditional rifling allows the use of leaded bullets - though I've shot thousands of lead rounds through oem glock barrels with no ill effects.
d) Supposedly provides better accuracy, but I've never had any problem with factory accuracy and this was not a consideration in my purchase.
 
Those grip changes for the GEN4 moved the G19 from being ignored by me to being a purchased gun. It didn't look like the first owner had fired it, but had added the Ameriglo I-Dot sights. Very nice, I think they are my favorite auto pistol sights now.

I'm going to take note of those two aftermarket triggers. They both look good to me.

The Glock striker is always partially cocked, it's just that pulling the trigger moves it to the rear an additional small percentage before releasing. In these triggers, it just increases the slight amount that the striker is already cocked, though it still maintains all factory safety positions.

The only 3 flat faced triggers like these that maintain all factory safety considerations are the Apex, Agency, and GlockKraft triggers. Suarez and the like bypass one or more of them in some fashion. I haven't used them enough to confirm, but Have tested and verified that at least my GlockKraft trigger still maintains them all.
 
additional small percentage before releasing

Partially true. The striker is about 50% precocked, with the rest happening as you move the trigge to the rear.

So, are you saying that the striker is cocked fully with these trigger systems?

Not sure what part was untrue about what I said.

No, they are not fully cocked. The striker isn't fully cocked until the cruciform releases it during its rearward travel.

It sounds like you have a decent understanding of how the Glock trigger mechanics work. There is some rearward travel before the trigger bar makes contact with the ramp on the connector which drives it down, forcing the release of the striker. In these triggers, they keep the trigger bar held rears to where the trigger bar is JUST BARELY not making contact with the ramp. So there is just a tiny hair of travel, then you hit the ramp(wall). From here you continue rearward travel as the connector ramp forces trigger bar downward, releasing the sear. There is still plenty of rearward travel once you hit the ramp, especially with the "-" connector which gives you lighter weight, but longer travel. With the factory connector, it's even more crisp, though heavier of course.
 
Uncle Malice, we got comments on our thread! I almost moved on and didn't come back to check on it. lol

Yeah, the threaded barrel was summed up already. More bullet twist without looking funky and yes, we do plan on suppressing our firearms at some point. I have a friend I go to the range with every now and again that has a suppressor for a 9mm that I like to run mainly on my SIGs.

Fun times! Thanks for the compliments.

If you have the chance to play with one of the cut-a-way models, you can clearly see the striker moving about 1/2 of its travel distance under influence of the trigger. Not a "small amount"...... 1/2 of its travel.

Does the new triggers additional "pre-cocking" effect the "drop safety"? That being the ledge the cross leg of the cruciform sear sits on until the trigger has past a certian point.

Nope. The same trigger bar and specs as the factory Glock ones. Only thing different is the trigger shoe. The drop safety is still there and still profound. I'd also like to add that it doesn't rattle or pinch your finger with the convex of the standard Glock trigger shoe. :)
 
Looking good, just got a Glock 19 gen 4, installed Trijicon bright and tough night sights, Ghost 3.5 connector, and Talon grips.
 
Thoughts from you gents on the zev trigger system in a glock? I am searching for a good trigger for my glock 34. The ghost pro 3.3 connector and springs have an odd feel and I'm not sure if I like it. If I decide I do like it I still want a nicer trigger and that "kit" can move down to my g19. I've looked into the agency trigger and the zev fulcrum, have never heard of glockkraft.
 
I've heard okay things about Zev, but I've also heard of them failing. I don't like adjustable triggers in any gun I'm going to carry. If it's for range use only, it's probably just fine.

GlockKraft recently changed their name to Overwatch Precision because they are releasing products for additional brands. Keep an eye for them. They have a fantastic product and are just a couple blocks away from Robar, so they work closely with them to have many of their parts NP3 plated.
