I've handled but not shot one! The slides are essentially the same as the D-W, but have the scalloped serrations on slide ala -945, and have pinned external extractor as D-W. They have the Briley bushing system instead of the NM configuration of D-W.
Also, the frame is not exactly 1911, (no seperate mainspring housing ala. 945, but takes 1911 mag release and magazines.
Fit and finish, were typical S&W Perf. Ctr. and accuracy should be same.. My two, soon to be three Perf Ctr. 9mm guns shoot ~1.0"@25yds, came with targets shot by Tom Gordon to back it up. My experience affirms too.
There will probably be a 6-8mo. wait for the guns. I was told to expect a 8-9mo wait on a 6" PPC-9 I ordered in October, by Beth Myette of S&W Perf. Ctr.
