CGW has developed a spring kit for the Sphinx SDP compact pistols. The out of the box DA is heavy as is the SA. Our new spring kit will significantly lower the DA as well as reduce the SA.
Plus we will be offering gunsmithing services soon. We have been given a Sphinx SDP and CGW has mapped out how to create an ultra-smooth killer Sphinx. Look for updates on our website in August 2014.
Great out of the box, and order of magnitude better when upgraded by CGW.
