I was not aware of this one. They made a 10mm/38-40 convertible at one time. The 10/40 should be a good combination.

I have owned a S&W 610 No Dash since they came out. I carried it for years as a Reserve Deputy. HOT 10mm for carry and cheap 40 S&W for practice. The 610 uses moon clips so no need for two cylinders.

Great find I am sure you will like it. Another advantage, if you spend much time at a Range you can pick up a lifetime supply of 40 S&W brass in a short time.
