I did a little research on the only revolver in his tests. He gives it a go - though he says that with 357 ammo it is uncomfortable to shoot.
S&W is having the same problems with the 360 series light-weights as they have with the air-weight revolvers. They break! It is common for gas cutting to erode aluminum frames and the air-weights have been breaking at the front of the top strap and through the threaded portion of the frame that connects the barrel to the frame. Apparently the 360 series suffers from the same problem. S&W tried to limit the gas cutting by cutting a notch in the underside of the top strap and gluing a piece of steel to prevent the erosion from the hot gasses but in doing that they further weakened the top strap!
The titanium cylinder erodes at the front from the hot gasses and the breach end of the barrel does too even though they are using "stainless steel". It is apparently not the same steel that Ruger uses in their guns.

even using exotic materials they still can't make a light 357 Magnum that stays together.
