Everybody has been voting for the Centennials, and I agree. Those are the ones with the totally enclosed hammer. I.E. the Models 40,42,340,342,442,640 and 642.
For a .38 Special I would recommend the M642. It is less likely to rust.
I bought a M640-1 .357 Magnum and a M642-1 .38 Special on the same day about 17 years ago. Never really carried the M642-1 very much but carried the M640-1 a great deal. I swapped out the rubber factory grips for a set of Eagle Secret Service wood stocks. They don't help with the recoil in a 23 ounce .357 Magnum as much as the rubber ones, but they don't catch on my covering garment like rubber does.
I have pretty much retired both of these since I got a M340PD a few years ago. It's an 11 ounce .357 Magnum Centennial, and it lives constantly in my left side pants pocket. (I'm right-handed). I put the wood Eagle stocks on it. It is actually painful to shoot with full power Magnums, which is what I always have in it. These are "shoot seldom, carry often" guns. I shoot them enough so I am totally familiar with them, but it ain't no fun!
The .38 Specials are pretty easy to shoot, even with +Ps and wood stocks. That is my recommendation.
