At a glance:
- Lighter weight for improved performance

- 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.

*Individual trigger pull weight results may vary.

Great quality, easy installation
My Victory has a super accurate barrel, I'd already installed the Trandemkross trigger upgrade and it was a big help, I decided to install the Tandemkross hammer and I'm glad I did. After installing the trigger upgrade, the trigger was significantly lighter but had a little sponginess to it, the hammer upgrade fixed that! The other handguns I shoot are mostly S&W revolvers so I,m picky about a trigger on a pistol. Installation is super easy, took a quick look on YouTube, very straightforward.

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.

Thunder
I have the race gun kit and hive grips with 5 mags including the tk bumper pads so I was already a huge fan of Tandemkross. I was lucky enough to get a Thunder hammer right after they listed on site. I absolutely love the trigger and hammer combo.. less than 2 lb trigger pull now is incredible! I was putting 500 rounds a week roughly through this setup and wanted to leave a review, however the site was giving me an error. I replied to their email and mentioned this along with a small issue i was noticing... to my surprise they sent me a new hammer!! Now that's service! I would recommend this product and this company to anyone!! A+

Mr.
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.

Works great
The Thunder" Hammer is great in combination with the Tandemkross trigger in my SW22 Victory. The pull is smooth with a solid break at release. My score at the recent 900 match increased by over 30 points from my prior 2 shoots. My trigger weight is a good 2lb 7oz (combined with the trigger upgrade). That stays above the 2lb requirement for NRA matches. I had 2 problems with installation. The instructions assume the magazine safety was removed, which is required for assembly (but not operation). The other is my pistol has a step at the hammer spring. When the hammer leans completely forward, the dangling bar traps on the step. The trick is to point the pistol up to release the bar. The bolt when assembled prevents the hammer from rocking so far forward. Great product for a great pistol.

Steel Shooter
I didn't think that it would be possible to improve the trigger pull on my S&W Victory after installing the TK Victory Trigger, but the "Thunder" Hammer did it! WOW! TK keep doing what you're doing, MAKING GOOD GUNS GREAT!

The thunder hammer is a great addition to the Victory trigger to drop the trigger pull even more for better performance & improved times.
