I have 2 revolvers both Rugers, both .357mag. One is a 4" bbl SS Security-Six, with the Pachmayer Presentation grips, and the other is a blued 6 1/2" bbl Blackhawk, to which I've added a 4x32 NcStar scope. I am interested in a Russian IzMech MP-412 Rex. It's a top break revolver in .357mag with a polymer coated frame and grip. It was available with 4" or 6" barrels. It never made it to the US market due to the Clinton / Yeltsin agreement, but it did make it to the European market. If anyone knows where I can get my hands on one, please let me know.
