The fit and finish of the Sphinx is absolutely great, but even with the spring kit the trigger isn't anywhere near my P-01. The lack of spare parts, no sight options, limited holster options and the previous track record of the Sphinx subcompact pushes me toward the CZ's. I do like the forward facing decocker on the Sphinx better than the rear facing lever on the P-01/BD. But, for me if I did buy a Rami I would personally opt for the safety model.
That makes sense and at least you have a point of reference with both platforms. Did David do your work or did you install the parts yourself? I personally have never been a fan of the Rami but I think it was the issues with the poly version that turned me off them. I have considered sending my Sphinx to David to let him "play with it."
