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.

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.

Thunder Hammer Upgrade
I installed the Thunder Hammer and trigger kits together and it took my Victory 22 to the next level in control and accuracy. The Thunder Hammer is a quality, precision built component. If you are a competitive shooter, or just want to treat yourself to a high quality trigger and hammer combination this is the way to go. The Tandemkross components and video allow for self installation, so while $65 might seem like a lot of money you will save more on not having gunsmith charges. I put the Thunder Hammer in two Victory 22's and I am 110% satisfied. I have spoken with the people at Tandemkross about the Thunder Hammer and other items I have ordered and I highly recommend them for the quality of their parts and for their excellent customer service.

Thunder Hammer for S&W 22
Works as it’s suppose to. A great addition to my pistol. Reduced trigger pull and smoothness.

Review
Great to have this as one piece that doesn;t come apart makes for easier maintenance. Performance wise trigger pull is reduced and it also feels like the break point is more consistent. The Victory trigger is a nice upgrade adding the hammer made this a very good consistent trigger. Nice upgrade

THUNDER HAMMER
Great addition to the trigger replacement! Breaks like glass and in conjunction with the trigger kit, reduced the pull to a just below 2lb average from a "Performance Center" 5 1/2lbs!

I installed the Thunder Hammer in my SW 22 Victory along with the Victory Trigger, the pair has made a great improvement to the smoothness of the action. Great buy, well worth the $$.

Thunder Hammer
Easy to install and seems OK but now I have a random problem of trigger not engaging. Doesn't happen all the time but as a competitive shooter this is entirely uncceptable. I have backed off the Tandemkross trigger adjustments but it still happens.
