TANDEMKROSS "Thunder" Hammer for SW22® Victory™ Installation Instructions
At a glance:
- Lighter weight for improved performance
- Reduces trigger pull weight and lock time
- Precision machined from hardened S7 tool steel for long-lasting durability
The SW22 Victory® features a good trigger out of the box, but even a good gun can be made great! Upgrading your SW22 Victory® hammer is a simple way to improve your SW22 Victory® trigger pull weight and transform your pistol into a shooting sports race gun.
The new TANDEMKROSS “Thunder” Hammer for SW22 Victory® is a drop-in replacement hammer that significantly reduces trigger pull weight.
The “Thunder” hammer is precision-machined from hardened S7 tool steel for improved performance. The lighter weight SW22 Victory® hammer reduces lock time and changes the angle of engagement between the hammer and sear, producing a crisper trigger break and lowering the trigger pull weight - ideal for Rimfire Challenge, Steel Challenge and other speed shooting sports!
Paired with a TANDEMKROSS "Victory" Trigger for SW22 Victory® , the "Thunder" Hammer can reduce trigger pull weight to below 2lbs!*
The "Thunder" Hammer features diamond-like coating for impact and heat resistance and also features an upgraded, dog-bone style strut pin. While the hammer can come apart into three pieces, the strut pin is designed to stay in place when under pressure, ensuring it does not loosen inside the gun.
For a full review of the impact the “Thunder” Hammer has on trigger pull weight, please watch the video above, or view it on our YouTube channel.
*Individual trigger pull weight results may vary.
Don't forget! All TANDEMKROSS products are Made in the U.S.A. and come with a no-hassle lifetime guarantee!

Hammer & trigger
What a vast improvement ! Dropped the pull to 2.1# -- and the travel of the trigger is very short.

Thunder Hammer
I replaced the rebound springs to complete the firing pin replacement I did in June. I was experiencing light strikes a lot. Replacing the rebound spring as well as the factory hammer, extractor spring and plunger seemed to have solves the problem.

Thunder Hammer
I was upgrading a used SW22 PC Victory that I had purchased and had already experienced a failure to eject and unintentional safety resets. I was ordering the Cornerstone Thumb Ledge (great product) and the Eagle Talon Extractor (another great product) and included the Thunder Hammer in my order. I was not concerned with trigger pull weight but simply wanted to refresh the entire unit while I was at it. Bill's instructional videos are excellent on all of the installs. I also discovered that a handgrip screw was stripped when I went to remove the Hive Grip, so also ordered the titanium torx head grip screws. All great products. Thanks Tandemkross.
