    Best Trigger Kit

    Posted by Daniel on Apr 29th 2022

    This is by far the best trigger kit to slap into your new glock. I've used the slimline kit and the fullsize kit. 10/10 just do it.

    trigger upgrade

    Posted by Mark whitwell on Aug 21st 2021

    I have used the grand master connector kit on my 43 and 48 Glocks. I am not expert at modifying weapons but with the help of a few videos I found it easy to install. I was in law enforcement for 28 years and the active duty/ guard military for 40 so have plenty of experience with trigger performance or lack of. The kit takes the glock from break the glass and use in emergencies to something that can be an asset when instantaneous, accurate and controlled gunfire is needed. My 2 cents worth

    Best competition trigger

    Posted by Hank on Aug 20th 2021

    This is my go to trigger for all my Glocks. The best drop in I have felt/owned. But it is very light, not for carry gun. When additional polishing is done you can create the smoothest trigger ever. Worth the try if your skeptical.

    With the Gran Master Connector Kit my Glock 42 trigger action has become smoother, crisper and lighter! Shooting performance has improved!

    43x trigger fix

    Posted by Tim on Apr 28th 2021

    Great for the 43x. The factory pull was mushy, sloppy and uncomfortable even with a Agency Arms drop-in. Adding the TTI Grand Master Connector Kit has made my 43x trigger pull crisp and reliable with a nice reset. Installation for me was easy, make sure you have a good set of punches and some tweezers. Start to finish took me about 30 minutes. Well worth the time, money and effort. Combine that with the great craftsmanship and customer service from TTI alongside better-than-expected shipping turnaround and this is an easy choice.

    Sharpened my Glock Trigger Nicely

    Posted by David on Mar 12th 2021

    I purchased this for my Glock 43 with the hopes it would clean up the mushy Glock trigger. I was pleasantly surprised with the result. Clean takeup, crisp break and nice reset. Worth the investment. I haven't tested the break pounds but I can tell it's lighter. But not so light that it's unsafe for concealed carry.

    Not as good as a ghost kit

    Posted by Unknown on Mar 10th 2021

    It did give it a better feel from stock. But not quite as good from other manufacturers.
