I'm wondering if any of you have done any chronographing of the 9 MM loads from a S&W 940. I am not sure that the .357 offers any power advantage over the 9 MM in these short barrels. If so I think it is marginal. I realize that if you get the absolute maximum loads in the .357 it would offer some advantage, but I don't think most of us use those loads in these light revolvers. I know that in my case the recoil is too punishing.
In the .357 640 2 1/8" with factory ammo I chronographed;
110 gr Hp Win White Box - 1185 fps
125 gr Speer GD - 1185 fps (in M 60 3" v = 1253)
158 gr Fed HS (Fired from a snub Taurus) 1178 fps
In a G 25
115 gr Cor Bon - 1277 fps
115 gr Rem +P - 1211 fps
124 gr Fed Nato - 1106 fps.
I realize that the barrel on the G 26 is longer, but considering the practical short barrel carry guns, there is not a great deal of difference in the .357 and the 9 MM unless one goes to something such as the 158 gr load.
It would be interesting to compare the 940 with the 640.
