I have a unit that is being utilized as we speak. It's awesome and mine is big enough for two 1911's. I highly recommend that you do not use blued steel with an ultrasonic cleaner. I don't know if my cleaner is super strength or what but it ate away the bluing on my recoil plug.
It takes 5 minutes to completely clean a pistol. This thing is great for revolvers! It's a shame mine isn't big enough to use with my Ruger Super Redhawk (7.5" barrel).
