I had one of the very early Witness .45s. I loved the ergos, but the workmanship was just so-so. I never could get 100% reliability from it, and accuracy was mediocre with most loads. Lots of vertical stringing, and it suffered from "1st round out" syndrome more than any other semi-auto that I'd had up until then. 3-4" high and right consistently.
I traded it on something else. Can't recall just what, though. I didn't think that I'd buy another Witness until I ran across a like-new 9x19 for $200.
That turned out to be a whole different story, with total reliability and superb accuracy with the right ammo.
I bought my 97B about a year and a half ago. The Witness 9 had taught me to appreciate the brilliance of the ergos and basic design, and the magazine reviews were encouraging. I really wanted that "package" in a .45 ACP, so I took the plunge again.
IMO, it's the best value dollar-for-dollar that I've ever had in a .45. It shoots as well as a custom 1911 that I have more than 3X the money in, fits my largish hand perfectly, and has proven to be 100% reliable with anything but "soft ball" target reloads. They just don't generate enough recoil impulse to cycle it all the time.
Newer Witness .45s may well be a different story, and around here they can be had for considerably less money. But I'd still pay the extra $100 for the best. It'd likely take more than that to get it shooting in the same league with the 97.
