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. Click here to read a full break-down of trigger pull weight testing on the TANDEMKROSS blog.

*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!

The TK Thunder Hammer is AMAZING!
I was honored to have received and reviewed the TK Thunder Hammer before the release and all I can say is WOW! This hammer is amazing! It reduced my trigger pull from 2 lbs to 1.5 lbs. It is very crisp and I feel that it made the reset shorter. It also had a solid hammer pin so you don’t have to worry about it crumbling like the factory roll pin. Whenever I thought you couldn’t make the SW22 Victory any better, then TK steps it up even more! This is a must have part for any competition shooter! Get yours today! Well done TK!

I ordered the thunder hammer for my victory 22 and had trouble with it not firing. I e-mailed Tandemkross and they were aware of some guns having this problem. They mailed me another new one and a return shipping label right out. This one worked perfect. Tandemkross was awesome as always. A great company with great products that they stand behind and are a pleasure to deal with.

Great Improvement!!!!
I have the Tamdemkross Trigger and put in the Tamdemkross Thunder Hammer. Great improvement from even just the trigger alone. Tandemkross makes great stuff for sure.

You can't go wrong
I build all my pistols into target pistols. I have two SW22 pistols with a Tandemkross trigger, hive grips, halo racker and the new thunder hammer.This hammer makes the difference between night and day especially with Tandemkross trigger.
