Must have to improve your 22/45

by Nico, Verified Owner from CA, United States Written on July 16, 2025
This kit takes out the magazine disconnect, and improves the heavy stock trigger by about 2 lbs. It's at a smooth 3lb pull now making a big improvement for a minimal cost.

Blast pack

by Red, Verified Owner from AZ, United States Written on June 19, 2024
I couldn't pass up the 10% discount on this item, The trigger pull on my Mark IV Target was more than I liked, 4.5/5 pounds. I wasn't ready to spend the money until I saw it here. It is tricky to install, just needs a steady hand and cool head. There are videos that go thru installing it step by step. After installing I now have a 2.5 pound trigger and the magazine disconnect is disabled. If the sear pin doesn't want to slide easily into the sear a small round file works to remove any burrs. All Blast pack Mark series sears have the same size sear pin hole. I called manufacturer because the sear pin was very tight, They sent me a new one free of charge. Then i decided to take a file to the one I have. It only took a few minutes. This item shipped very fast and happy with my purchase.

PITA to install, but a great upgrade nonetheless

by Ooga Oogaboogavich Oogaboogovsky, Verified Owner from NV, United States Written on September 16, 2023
As the title implies, be prepared to do some work to get this bad boy in your gun. However, combined with the Tandemkross victory trigger, it significantly improved the quality of the bad stock trigger pull on the Ruger Mk. IV. Would recommend.
Pros:
  • Much-improved trigger pull
Cons:
  • Moderately difficult installation

Does a Great Job

by hays47, from OH, United States Written on March 16, 2023
Modicum of skills needed to install. Not overly complicated and greatly improved the factory set up. Later on I installed a Victory trigger and was rewarded with great performance. Suggest you watch Tandemkross installation videos and follow hints and suggestions.

Sear pin issue

by Fenndaddy1, from WI, United States Written on February 11, 2023
Installing the sear uses the stock sear pin. My stock sear pin would not fit through the new sear. It started but got stuck. Couldn’t tell you anything else because I couldn’t finish the install. I’ll return the item and ask for a replacement . Maybe it was a fluke.
