Thanks for the feedback. What if I get a barrel that's longer than the snub? Will that make it more accurate out to longer distances? How does the barrel length affect performance?
Rob87,
Barrel length won't make a revolver more or less accurate. I know you will hear things like "a snub nose revolver isn't accurate" but that's not true at all. The fact is a revolver with a 2" barrel is more difficult to shoot well because of the short sight radius. Little mistakes are exaggerated due to the short barrel and will show up the further the target is from the gun. A 3" or 4" barrel revolver has a longer sight radius making it easier for the shooter to shoot well but like I said, the revolver itself is no more accurate because of the barrel length.
Since you said you will be carrying this revolver on your hip any J frame will be fine. If you want a light .38 Special buy a 15oz S&W Airweight. (M442, M637, M638, M642) If you want a Stainless .357 Magnum buy a 23oz S&W M60, M640, M649 or a 26oz Ruger SP-101. If you like something in between the S&W M36 and M40 are 20oz revolvers.
All will serve you very well and for the most part it will come down to how heavy you want your revolver to be and which frame you like best.
The Chief's Special frame has a fully exposed hammer. They are the M36, M60, M637 and the SP101 (KSP-321X).
The Bodyguard frame has a shrouded hammer yet still allows for both SA and DA shooting. They are the M638 and M649.
The Centennial frame has a fully enclosed hammer which allows for DA only shooting. They are the M40, M442, M640 and M642. Ruger's SP101 (KSP-321XL) is a DA only revolver but the hammer can be seen when fired even though it's flat to the revolver.
Now if all of that wasn't confusing enough I have one more option you might want to consider. The SP101 with a 3 1/16" barrel in .327 Federal Magnum. From everything I've read you get almost .357 Magnum power with 20% less noise and recoil. If you want to look at this revolver
