    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!
