Fits ALL Glock Models (Except Glock 42/43/43x and 48)

This is the connector long sought after by Glock Enthusiast everywhere. This is the Lightest Smoothest Connector on the market today 3.3 Pounds.


  • Lightest Stage Free Trigger
  • Smoother Than any other Trigger
  • Shorter Pull Eliminates Over Travel
  • Perfect Function
  • Fits GEN 1-5

The GHOST PRO 3.3 is the best self-defense & Target trigger control connector Ghost makes!

The PRO 3.3 is Smoother, Lighter, Shorter and eliminates trigger Over-travel! These attributes give you the fastest most accurate first shot hit advantage of any self-defense Glock style trigger.


The PRO 3.3 fixes the Glock bump or glitch, this is the pre-travel resistance you feel and must overcome when the trigger bar bumps into the connector. This bump causes you to apply excessive force and will move the pistol off target. Another thing the PRO 3.3 corrects is trigger over-travel; the excessive movement of the trigger after the pistol fires. Over-travel causes the pistol to move off of alignment with the target, making your shot go low and to one side.


The PRO 3.3 is the best self-defense connector made and by changing a few springs you can also have the best sport trigger connector! We believe that this trigger control connector makes all others obsolete. Once you try it, we know you will agree! Minor fitting required.

Ghost Complete Trigger Spring Kit

This is a complete drop in trigger kit is designed to help you fine tune and improve your trigger pull, and function in competition pistols, and for Self defense Carry or Hunting pistols.

Included in the kit are 4 Drop in Springs:

  • 4lb Reduced Power Striker Spring- Should only be used for a strictly target or competition set up.
  • 6lb Extra Power Striker Spring- Use this to increase the strike power and makes for a faster reset.
  • Reduced Power Safety Block Plunger Spring- Smooth out the bump as the safety plunger is engaged.
  • 6lb Extra Power Trigger Spring (Extra power reduces the pull weight)- This heavier weight offsets the added weight of the striker. This is an assisting spring and lightens up the trigger press. This spring is not used on Gen 5 Pistols.


The Ghost Complete Drop in Spring Kit gives your Glock a smooth, crisp, lightened Trigger pull that helps promote consistent, match-grade accuracy. You can change specific springs to improve a particular aspect of the trigger pull, or do a complete upgrade.

Accurately calibrated spring weights deliver consistent force through the entire compression and release cycle to give you a light, refined trigger pull without sacrificing the reliability of your pistols Safe Action system. Trigger Spring has nearly 30% more power than factory spring, which actually reduces pull by as much as 1 lb. for improved control. This produces faster trigger reset for quicker follow up shots. Reduced power Safety Spring reduces friction caused by the firing pin safety, further smoothing the pull. Striker Spring is designed for improved consistency and durability over factory spring.

You can choose the Competition Lighter Striker Spring or the Heavier Self Defense Striker spring.

This Connector is For Competition and or CCW Self-Defense.

Recommended: A gunsmith or armorer should install this connector.



Please Note: The 4.0 lb Firing Pin Spring may cause light primer strikes in some pistols and this is the Target/Sport configuration. For Self Defense or in a 10mm/45 caliber GLOCK we recommend the 6.0 lb firing pin spring or keep stock firing pin spring and use the 6lb. trigger spring and the reduced power safety plunger spring.

  1. Does what it says 4 Star Review

    Posted by on Sep 8th 2021

    First off, it did provide a slightly lighter trigger pull, but as I was focused on improving a daily carry, so I used the heavier striker spring. The difference is minor, but noticeable. I had to remove quite a bit of material to set it up, but there is absolutely a shorter reset now thanks to less overtravel. If it doesn't feel quite right, you probably need to remove more material.

  2. Fourth 3.3 I've installed! 5 Star Review

    Posted by on Feb 17th 2021

    Taking a 17 or 19 off the shelf and installing this TCT and spring kit makes it seem like an entirely different gun. There really is not way to convey the amount of difference in the feel of the trigger this kit makes. I let buddies use my 17 at the range and was immediately asked to do the same to their pistols. Have also installed into a G43, very easy to do but the grinding is a little different. This is the best I have found and it is pretty cheap too. I used a marker on the TCT then grind the mark off. Took a little less than an hour…not hard just time consuming. Having to assemble and disassemble…does take time.

  3. Amazing end results 5 Star Review

    Posted by on Dec 12th 2019

    Amazing results !!
    I installed the 3.3 kit in a G35 gen 4 and i can't believe the difference, it's a totally different gun

    I also had to take quite a bit off the tab in order to get the striker to fire, but once it got it trimmed down it was just phenomenal how much better the trigger was.
    For me, it was about 5-6 dis assemblies to get it were I wanted it
    Very Very smooth NO wall at all very clean break
    I also did a G43 (Edge i believe) with really improved results as well
    Outstanding customer support from Oliver

  4. very pleased 5 Star Review

    Posted by on May 26th 2019

    I took me about 2 hours to do this upgrade after watching the videos. I was surprised that even with the short backplate I wasn't able to release the trigger with out taking off the backplate and pulling out the trigger until I had filed quite a bit off the tab. However, once done, it is a great trigger, with no over travel or stacking. My groups definitely improved. The trigger is a pleasure to shoot now compared to the stock trigger. Model 34 Gen 4

  5. Pro 3.3 kit in my Gen 5 5 Star Review

    Posted by on Mar 26th 2019

    Works very well in my Gen 5. Now a much better trigger pull. I took my time with a dremel. I had to disassemble and reassemble it many times to get it just right. I am very happy with the Pro 3.3 kit.

  6. The Best 5 Star Review

    Posted by on Feb 4th 2019

    By far the best triggers and customer service I have ever experienced. Oliver was incredibly helpful and informative. Thanks again!

  7. Smooth overtravel 5 Star Review

    Posted by on Apr 2nd 2018

    The Ghost Pro 3.3 installed easily and took only a modest amount of fitting. There is now no overtravel, short reset and smooth trigger pull. The trigger weight has not been measured but feels lighter than stock and is significantly smoother.

  8. Best Upgrade for Glocks (IMO) 5 Star Review

    Posted by on Jan 29th 2018

    Everything Ghost, Inc says about this trigger system is correct. The effect on shot-placement accuracy is profound. My Glock-40 (10mm Auto) shoots as accurately or better than my Colt Delta Elite (10mm Auto) with a Nowlin barrel & Ed Brown internals. If I had not experienced the improvement in PoA control brought by eliminating over-travel, I wouldn't have believed it. The Ghost Pro 3.3 trigger makes Glock's DAO trigger work as benignly as a good SA trigger in terms of PoA stability through the trigger-pull process. Highly recommended. I'm putting the Ghost Pro 3.3 in all of my Glocks now. RiP

  9. Best Connector 5 Star Review

    Posted by on Jan 10th 2018

    So linear, so smooth. Like a different gun. Once fitted, overtravel is gone forever and no more wall to affect keeping the sights on target during the trigger press. 100% recommended.

    Ghost sent me some swag too!

  10. Connector Pro3.3 As Advertized! 5 Star Review

    Posted by on Sep 5th 2017

    Glock 29 works perfect, You must cut fit tab as per Ghost online instructions. I measured the Oem set up on sear, trigger housing width with Oem connector, & transfer bar to frame clearence before installing Pro3.3 Connector TCT. Second cut on TCT did the job. No Creep, breaks as advertised.
    Very Good Product, Would buy again for my next Glock! The kit has every thing need to install.
