I traded away my Witness Sport Long Slide a couple of weeks ago, for a ANIB (less than a box of ammo through it) SIGPRO 2022 (.357 SIG).
Lots of folks sneer about the "PRO"-series SIGS, but I like them.
I wasn't shooting the Long Slide (after getting my SIG GSR), and was hankering for something different. I didn't really want a .357 SIG, but thought. "What the hay?" It was offered as an even trade, and they were comparable in value. (Maybe a little less, as I threw in 3 extra mags.)
This gun came with night sights and 3 x 12 rounds mag. It has the stock extra/alternative grip.
I've been pleasantly surprised:
1) typically top-quality SIG fit and finish, despite the polymer frame.
2) fair double-action trigger, nice single action trigger. It can only get better. May or may not get a trigger job.
3) Surprisingly, more pleasant to shoot than the other .357 SIG guns I've tried.
4) Only the second gun I've got (the Glock 34 is the other) that lets me work all of the controls without changing my grip. (The slide release is particularly easy to activate.)
----------------------------------------------------------
I never shoot a new gun well the first time out -- it usually takes a couple of range sessions for me to adjust to the gun, but I was doing pretty well with it -- at 30': about 1/2 the shots in a small group in the black, with the other 6 trailing down to the left. I suspect I was anticipating recoil. Despite that, it had a suprisingly mild recoil with the polymer frame.

I may offer this one up for trade, one of these days, after I get tired of paying for .357 SIG ammo.
