    Super easy to install. Prefer this rather than another manufacture's trigger kit that includes a new firing pin. Sphinx quality doesn't need a new firing pin. Just springs to lighten up the DA. This does the job perfectly and does it for a perfect price. Really helped the DA pull. Didn't think the SA improved too much as it was already pretty nice. Overall it's a must have!

    Very easy install, though a print out for the firing pin spring would be nice. You can feel the signal action reduction slightly. The real improvement is with the double action. Much lighter and smoother. Absolutely worth the $20 price tag.
