So I've got two:
A Fusion Riptide C in 45ACP, and a custom 9mm commander.
The custom is amazing - great shooter, perfect trigger, beautiful, perfectly dehorned. I just can't get it to feed reliably with everything as I would expect it to. So it'll be on its way back for tuning or (probably) replacement of the current un-ramped barrel with a ramped one. I've probably got 300 rounds through it and I keep thinking it's some combination of bullet weight, spring weight, and magazines it likes so I haven't sent it off yet.
The Riptide has been great. It's not exactly comfortable, but the stippling has enough "bite" to give a great grip regardless of conditions without damaging your skin. It's a fine line, and I think they walked it well.
As Iggy said, the guy who ran Dan Wesson before CZ bought them out started up Fusion.
