I do not, however, have any experience with the new "Wizard" line.
I can't speak to the Wizard as a complete firearm, but I've got two Wizard barrels, they aren't close to fitting one of my frames with the same shim, one works great, the other won't come close to fitting, so how in the world could they be switch barrels which they claim?

Seems to me they must have some serious quality control issues, of course this is a small sampling, and all mfrs make a lemon once in a while.
