Dave Lauck produces left-hand S & W revolver conversions (Custom Revolvers - 1st thumbnail 1st row). He is a true master craftsman - his work is exceptional - but it will cost you.

The competition left-handed revolver pictured costs $2,750+. A complete personal defense/close-quarters battle (CQB) package costs $2,200. He quotes the following on his site under "Guns Currently Available": Custom S&W model 625 SS .45 ACP revolver $1850 - as he explains this is a forfeited project that reflects a deduction of the initial deposit paid - even with the deduction it is still expensive.

Except for the last item above I'm almost positive that the prices DO NOT include the cost of the base revolver! Like I said his work ain't cheap! However, I've never heard anyone complain - about anything.
