As a fan of 9mm auto pistols, I am a big believer in consolidating calibers, so the S&W 940 has interested me for years. However, I never see one for sale and assume they must be scarce indeed. For those in the know, I have the following questions: how long was the 940 produced, and is there a gunsmith who can convert a J frame S&W to shoot 9mm ammunition?

Thanks in advance for your thoughts / assistance.
