OTs-38 Silent Revolver

I thought the Nagant M1895 revolver was the only one capable of using a sound suppressor.  Apparently there's also the OTs-38, which has an integral suppressor.  It fires through the bottom cylinder, like the Mateba and Rhino.  The cartridge is 7.62x42, and appears (from the photo) similar in shape to the 7.62x38R cartridge except longer and without a rim.  I'd love to get my hands on one of these guns!
