    Works great as expected

    Installed in conjunction with new trigger and was very pleased with results. Very smooth and consistent pull, slightly lighter than stock with smoother 2nd shot. About 500 rounds through so far with no issues.

    G48 MOS what it should be

    Posted by RKHarm24 on Jul 28th 2021

    My G48 MOS had a trigger that stacked like a large pile of rocks. Ordered this spring kit and the connector from TT. After arrival I installed and skeptically held my breath as other "Aftermarket Parts" were duds. SURPRISE! These few parts turned my 8 or 10lb trigger into a smooth firearm tool. As nice as my broken in G45. My 43x didn't get the connector but it will soon. I did order 2 of the spring kits. The 43x is much better but the trigger stacks at a wall but clean. Thanks crew at Taran Tactical for making my G48 and G43x what they should have been from the get go.

    Number One Glock Upgrade for the $$$

    Posted by David J Colombo on May 12th 2021

    Just purchased my 5th TTI Ultimate Spring Pack. For the cost, it gives the single greatest value for a Glock upgrade you can find. Every Glock I purchase, I get new sights, the Spring Pack and a different trigger bar and shoe. Each and every time. The spring pack makes a huge difference and I can't imagine any of my Glocks without it.

    Cheap fix for crunchy glock trigger

    Posted by Chris on May 6th 2021

    Worked so well, I didn't need to purchase a disconnector. A 10 minute job max.

    Best upgrade out there

    Posted by John Harris on Feb 5th 2021

    This was a game changer for me. I have weak hands due to a disability. Making this change it has allowed me to shoot even better than I could at my best before the progression of my muscular dystrophy forced me to have to overlap fingers to shoot efficiently. Now I am able to shoot with just the use of my trigger finger easily and accurately. I absolutely swear by this product and I am in the process of transitioning all of my Glocks to these springs. Customer service is top notch also.

    glock 43x, terrible factory trigger, changed out the springs and other parts, 3.5 pounds consistent, much smoother overall operation

    A must if you want a lighter trigger

    Posted by Kevin Tran on Aug 17th 2020

    Can't beat this for the price. Weight drops down and makes the trigger comparable to custom drop in triggers. I personally shoot better with guns that don't have a hard wall stop before the break. This fixes everything.Pair this with the TTI connector and you're golden. Just a heads up, if you don't like light triggers, this will not be for you. Extra trigger discipline is a must on this.
