Review of Tandemkross Victory Trigger

TL;DR – 10/10 – Worth the hassle of installation.

Yesterday I received my TK Victory Trigger and Challenger Charging Handle. I also run the Tandemkross Game Changer Pro. Last night I installed the trigger. I have zero gun smithing knowledge and after reaching out to TK they published the installation instructions and video.

The most challenging part of the install was removing the roll pins to pull the trigger assembly. Even with a punch it was a lot of work. I ended up leveraging my bearing press and some chunks of wood to press the pins out. Once I got the them out, I followed the instructions and installation was a breeze.

One thing I did notice was the instructions have you install the set screw that preloads the trigger from the top, which is what I did, but unfortunately makes it impossible to adjust without disassembling the gun. It feels like their installation was meant to have the head of the screw exposed in the trigger body but after testing, there isn’t enough clearance to do that.

With that said, expect to have to take the trigger out multiple times to get the adjustment of the preload perfect. Don’t push your pins in until you dry fire it a few times to make sure it feels good. 

Once the trigger is installed you can adjust the trigger pull with the trigger installed. I ended up breaking two roll pins installing them back in. Harbor Freight sells a set of roll pins and it includes ones that are perfect, I think they are the 5/64 x1 pins. They seemed to install fine and be more durable than the stock pins.

The Challenger Charging Handle took about 15 seconds to install. Press an Allen key in the rear hole, remove the stock peice and replace with the charging handle. 

Today I took it to the range today and I LOVE the way it shoots. The preload was always annoying, having to pull the trigger in what felt like an inch until just before the point of firing made for a not so great pull. It’s worth noting that this is a safety feature that you are bypassing.  

With the Victory trigger, I have the preload adjusted to right before the trigger is engaged, allowing me to simply squeeze the trigger and shoot. It is a VERY crisp feeling shot with the new trigger.  

The texture of the trigger is a lot more aggressive than the stock trigger, allowing for a positive and repeatable finger position.  

Was the trigger install worth fighting with the roll pins and having to buff out a few slight cosmetic scratches on the lower assembly? While I am a novice when it comes to firearms, difficulty in installation is in no way the fault of TK, and from a product standpoint, I say yes, 10/10.
