Fit my hand well, shot well. I used mainly Federal 9bple. One of many I regret getting rid of. As I recall it was developed as a sidearm for USSS, but they went with Sig 228's
Beside being very thin for a wondernine, by turning a selector with a screwdriver, you could switch from Da/Sa to DAO.
I picked it up today. I went straight to the range and lubed it right on the line and put a few mags through her and it shoots at least as well as my SP-01 custom target. I may have a new favorite! The only con is the LONGGGGG double first trigger pull.
