WTT: .38 Smith & Wesson for .38 Smith & Wesson

[Niederlander]

Gentlemen,  I've got a Smith & Wesson .38 Hand Ejector, M & P 2nd Model, marked for .38 S & W Special or U.S. Service Cartridge, with a 6 1/2" barrel, blued, with a beautiful bore, decent finish, and very nice wood grips.  As I shoot it a lot, I'm a little concerned about it breaking and no parts available.  I'd like to trade it for a 4th Model with a round butt, and 6" barrel, preferably blued.  Let me know what you have!
