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!

Smashing!
My Victory is blessed with a 1.1lb trigger pull with the Thunder Hammer and TK Trigger (gotta love red triggers!). I love my Tandemized Victory.

Thunder Hammer
As advertised. I had Several cycling issues from the factory pistol. After a few upgrades from Tandemkross including the thunder hammer ive went to having zero issues. I highly recommend the thunder hammer.

Thunder Hammer
Installed the Thunder Hammer after installing the Tandemkross trigger several months ago. The trigger dropped the pull weight from 4.5 to about 3.5. Adding the hammer, which was a much easier install than the trigger, dropped it to about 1.9-2. Nice and crisp let off with no creep. If you want an inexpensive target trigger on your Victory this combination can't be beat. Be careful letting your friends try it though. If they're not used to a really light trigger they'll have a tendency to double until they get used to it.

Power Hammer & Pro Compensator
My S&W OEM hammer was significantly worn after 10 thousand rounds.The TandemKross power hammer and a deep cleaning of gun greatly helped decreased the number of misfires using CCI Red Clean ammo. I was having 5-6 misfires out of 100 rounds now down to 1 misfire per 100 rounds after installing new hammer and adding Pro compensator.

Easy install hammer with a glitch
The hammer was a simple install, all 3 times I did it. Yep, 3 times because it wouldn't work. See, nobody tells you that the strut can fall out of place but the hammer will still install. It just won't move. Remember to make sure your strut is sitting on top of the mainspring and that the hammer does clock before you reassemble everything. Other then that the hammer is a great light weight product.

Thor's Hammer
The Thunder hammer for the SW22 Victory is amazing! I had some minor issues during the installation - it appeared to hang up. I got it moving within 30 minutes. The item shipped in a nice presentation box. After opening it, you'd swear that Thor personally handed you his hammer! When combined with the Victory trigger, the Thunder hammer significantly reduced my pistol's trigger pull weight down to 1#! The pistol operates without issue during live fire. Seldomly, the hammer will hang during my cleaning and maintenance procedures. If it were not for the hang ups, this item would get 5 stars. Otherwise, it is a stellar product that gets 4 stars.
