Review
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
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.

Replacement for lost parts
At some point I lost the spring and the spring support and didn't even know. These springs are like factory original. Wish you supplied the support part as well.

Rebound Springs Didn't Fit
I needed a new rebound spring after 20 years of shooting my Mark 2 22/45 and saw a TandemKross Youtube video. I figured I'd give their springs a try. They showed up and didn't fit. I contacted TandemKross and was told that Ruger has changed the dimensions of the Rebound Spring Support. The springs now have a smaller inner diameter than previously as the support is thinner. I contacted Ruger and they sent me both a spring and the support. I'll hang on to the TandemKross springs as they now fit the support Ruger sent. Not really TandemKross's fault, but it would have been nice for their page to mention the springs don't fit older pistols.

Rebound Springs
These springs are close to original. However they don’t have the tapered end like the factory springs do. They work fine and are the only springs I could find online. I shared some with a friend. Good part to have a few spares on hand!
