    Rebound spring

    Posted by Christopher on 25th May 2022

    Who would have thought that such a spring would cause so many problems before being replaced...after 30K+ rounds through my MKiii, I was having issues with a lot of light strikes. I replaced the hammer spring assembly, and that fixed most of the problems, but I was still having light strikes. People I shoot with suggested replacing this spring, and I have yet to have another light strike again. Since it was a 5 pack, 2 others in my group benefited with my purchase.

    After a few thousand rounds was getting light primer strikes. After switching around ammo and cleaning thoroughly the problem persisted. This eliminated the issue entirely. Thanks again Guys

    Ruger 2245 rebound spring

    Posted by Rick on 9th Mar 2022

    It was a pleasure doing business with Tandemkross. Everything fit and worked as it should have. Customer service was great. My best advertisement for them was to put their decal on the front of my shooting box.

    Lost a spring while doing a deep cleaning. These replacements fit perfect, just a drop in installation. Pistol works great with the replacement no issues at all.

    Rebound Springs

    Posted by Diocoles on 2nd May 2021

    The package contains 5 rebound springs. Work great. Easy to install. The only negative is that you don't sell the rebound spring holder to go with the springs. Springs without that holder don't do the job. Springs are good quality though.
