I still have my OTHER Sphinx. <grin>
But I've been going to school at night/on line for about 2 years, and haven't really done a lot of shooting (almost none) -- I just haven't had time. I will be retiring in a month or so, and I hope to finish up my schooling in the spring (possibly, before that.) I may then have some time to shoot again.
(And by mid-year, next year, may be lokoing for a teaching job at on of the Junior colleges or community colleges in the area.)

The instructions on how to do a trigger job may be all you need, in the FAQ area. That and a slightly lighter mainspring.
The most important thing you can do for carry is spend some money and get yourself a very comfortable, well-designed IWB holster. Leather, if the climate in your area allows it -- they're just more comfortable (IWB). You'll carry it a lot more than you'll shoot it.
