Frankly, I would carry neither of them.
The best reason in the world for carrying one of these small guns is the .357 Mag 125 grain JHP loads. Why carry a gun this size and carry anything less than the best stopping ammo?
A stainless Model 60 .357 2" barrel, LOADED weighs less than 25 ounces. This is not heavy, and delivers real stopping power.
I do have a titanium revolver, the Taurus 450T, and it delivers essentially the same power level and weighs within a fraction of an ounce of the model 60.
The downside is finding decent ammo in .45 Colt, and the gun is a bit bulkier (cylinder sized like an S&W 686, and the big Ribber grip). The upside is that the muzzle blast is much reduced, muzzle flip is reduced, and the grip is MUCH more comfortable.
Lets face it, if you want 500 ft-lbs. of energy (and you should) than a 25 ounce gun is just about right, light enough to carry, heavy enough to shoot.
