The Downsizer Corp in Santee, CA made and delivered a handful of its WSP models for a few years before SB15 became law and production stopped for good. I believe fewer than 100 pistols were delivered up to that point. Whatever the exact number was, it was’t very large.
The WSP model received lots of positive reviews after they were introduced at the SHOT Show (1998, I think). There is a very detailed article by Robert Hausman in HANDGUNS 2001.
