Excellent Trigger
I only Use Mcarbo in all of my Custom Builds. Mcarbo is the best. I have tried other Brands was not Happy. Mcarbo covers every I am looking for. When you want the best should be no question Mcarbo all the way, I recommend Spring Kit to get full Potential out of the Trigger It does help and you will not be disappointed.

Handle with Profession
I had a issue with a Glock trigger awhile back, I was contacted by Mcarbo and Issue was handled Professionally and with out question, My past review was on that 1 Trigger I've never had any problems what so ever with a Mcarbo trigger. I'm not a happy gun owner wanting to do a DIY I'm a Certified Gunsmith who has installed countless Mcarbo triggers in not just glocks many brands of guns

Quality had the day off
I must start this review by stating this is my first issue I've ever had with Mcarbo. I recently purchased a Trigger for a Glock Gen 3-4 to be installed in a Shadow Systems MR920. my Customer loves Mcarbo triggers and have installed them in customers Sig Sauer and Glocks. Not just 1 or 2 in the Multiples of combined 12-13 triggers, they purchased them for family members and he has combinations of same gun with different accessories but always with the Mcarbo Trigger. When I received the trigger I do full checks and when need be change the trigger bar as well, On this particular trigger I noticed and could not remove trigger bar screw due to it was rounded out and stripped out, I contacted Mcarbo and only assistance I was given was to use a Rubber band along with with the tool to take out screw, ok then what do I use same method to reinstall it. no solution was offered by Mcarbo after many emails written, Now I can't guarantee the quality of this trigger to function properly this is now a safety issue. hopefully Mcarbo will do the right thing

Trigger safety doesn’t work
I’ve ordered from Mcarbo many times. I’ve always liked their products. However this one doesn’t work right and I’ve got $100 useless trigger. I got a response saying weak striker spring. Nope. Tried with multiple slides. Should be popped out and I can push and it feels tight. Something is not right. Had a Timney that wasn’t right and they sent another. Guess this was my last Mcarbo order
GLock Omega Trigger
Bought this for my Dagger and man it works great!!! Super happy with this upgrade to a very economical gun purchase.
Absolutely phenomenal
I replaced and already fantastic aftermarket trigger with this offering from M*CARBO and the improvement was notable. Further reduction in pull weight, a vertical break point and the pre/post travel screws took all the unnecessary travel out of the trigger. The jig that’s included is great - makes install a breeze. Can’t wait until they make one for the Gen 5 guns :wink: :wink:
Easy installation, easy over travel adjustment with supplied blocks.
Decreased my trigger pull substantially with nice break and reset.
Slick Trigger
Adjusting the trigger was easy with the provided aids. Final result after polishing was a little over 3lb pull.
Has this been tested to work safely in the new Ruger RXM (which uses the Gen3 trigger system)?
The Ruger RXM is designed with a modular Fire Control Insert (FCI) that closely mirrors the Glock Gen 3 architecture. This design choice allows for the integration of many Gen 3-compatible components, including trigger assemblies.? Users have successfully installed Gen 3 aftermarket triggers in the RXM without issues. For instance, one user reported:? Brian Enos Forums - "I've installed an Apex Enhanced Trigger kit made for Gen3/4 Glocks in my RXM with no issues. It drops right in." ?Brian Enos Forums. This suggests that the M*CARBO Omega Competition Series trigger, which is a drop-in replacement for Glock Gen 3–4 models, should also be compatible with the RXM.
Hi, I see where it says not for 10mm but if I buy the setup for Gen3 trigger and bar why would it not fit my G20, 10mm? When I buy factory trigger w/bar and order for Gen2,Gen3, Gen4 it doesnt specify a different trigger and bar for G20, Gen2, 10mm.
Am I missing something? I bought a G.S. Pryamid Gen2 and with several connectors it fires on reset every time and cant have that so returning and fimd something else.

Glock 10mm models like the G20, G29, and G40 use a wider, large-frame receiver (same as .45 ACP models like the G21). The Omega Competition Series trigger ships with a Gen 3/4 9mm/.40 trigger bar, which: Is narrower,
Has a different angle and length for the trigger bar “cruciform”, Won’t properly align or engage the sear/striker lug in a G20/G40 frame.
shadow systems runs off a Glock Gen 3. does this trigger work in full size and compact
Yes — the M*CARBO Glock Gen 3-4 Short Stroke Flat Trigger (Omega Competition Series) will work in both full-size and compact Shadow Systems pistols, with a few conditions: Shadow Systems’ Internal Tolerances:
They often use tightened tolerances and custom striker assemblies, which means: Always verify full trigger reset and safety engagement after installation. You may need to lightly adjust pre-travel or overtravel screws to dial it in.
Recently purchased this and saw there was a card inside saying there is an installation video pointing to a sticker with a QR Code on it. Unfortunately the QR Code is too fuzzy and faded to be scanned by any of the phones we tried with. Do you have a link to it somewhere?
At this time we do not have an installation video for this item. We should be uploading one within the next month or two.
Guys, I liked this trigger kit so much (along with the spring kit) when I installed it on my Glock 17 Gen. 4 that I bought the same kits and recently installed it in my Glock 22, also gen. 4. However, I’ve discovered a difference between how it’s working in the 22 that isn’t found my 17: the gun works just as excellently as the first gun, except that if I dry fire it, keep pressure on the trigger and not allow it to reset, rack the slide again, the striker “fires” as soon as I allow the trigger to go forward and reset.
While some would be tickled pink by the addition of this fortuitous “new feature”, I’m a bit concerned from a safety point of view. Has anyone else reported encountering the issue? Do you have an idea about what could be causing this?

I just bought the trigger also the polishing kit. Is trigger bar already polished? I am wondering if this item need polishing as well.
The Trigger bar comes unpolished from the factory
Gen 2 g20, is that type trigger available for the g20
No — the Omega Competition Series Trigger is not currently available for the Gen 2 G20 (10mm)
The PSA Dagger uses Glock Gen 3 parts, will this trigger work in a PSA Dagger?
February 10, 2023 6:19 PM
It will fit. Although, it may not be drop safe with the PSA DAGGER Glock clone. Due to PSA tolerances, we have seen cases where the cruciform does not sit firmly on the safety shelf.
Very interested in buying but may wait if a video on installation is soon coming. Step 3 and 4 are not as clear as I'd like them to be.
We have the plan to make a video, but other videos are being prioritized due to being easy to installation If you have any questions, you can contact us at help@MCARBO.com, and the technical department will be able to help.
Will this drop in fit a G28?
That's a unique one! We haven't had the opportunity to get our hands on a G28 so I am unable to say. If the internals are the same as the G26/27, then it will.
Judging by the dates of the questions and answers, I assume this is a fairly new item for the MCARBO inventory. So, is there a Gen 5 compatible unit on the way anytime soon?
We are entering the Glock market strong. More products are on the way!
Will a version be available for the large frame pistols? I have a Glock 20 10mm
Will this fit a gen 1 9mm?
No, these are designed for Gen 3-4 models only.
Will this fit a polymer 80 PF940v2 frame?
We have not tested it in P80 frames as of yet. We have tested on the PSA Dagger and Shadow systems with success but our engineers are still currently undergoing testing for the P80 variants.
Will this work on Glock 19 Gen 5 ??
It does not fit Gen 5, only Gen 3-4 as per the description.
Is this a drop in trigger install for a gen 2 glock?
Will this fit and work properly on a Gen 3 G35?

Will this fit a Glock 21 gen 4?

the Palmetto State Armory Dagger, the M*Carbo Glock Trigger Assembly GEN1-4 is functional in the PSA dagger, but due to not meeting M*Carbo safety standards, the M*Carbo Glock Trigger Assembly GEN1-4 shouldn't be listed as compatible with PSA Dagger
