This morning a lady student came out to do some more break-in on a new Kahr CW9, so I set up the chronograph in advance and used the opportunity to do the testing below. The "standard velocity" shown is the same 124 grain load I've had in PM-9 for several years. The CW9 had only 100 rounds total of WWB down the barrel before the Gold Dots were fired. The other 2 pistols are far more broken in and were semi-dirty at the time.

The short-barreled 135gr. .357 is the only .357 I find really manageable in my airweight S&W 340PD. It definitely burns better than full-power .357 in such a short barrel. I've used the .38SB load in my .357s, but since I don't have any .38 J-Frames, I don't see a reason to use it over the .357SB load. I had no issues with it though, it it's probably what I would carry if I had any .38s.
