I have noticed that Sierra offers a 124 and 125 gr. bullet in .355". I couldn't tell much difference from online pictures. But then I came across this article;

Now I have purchased the 124 gr. but the 125 gr. seems to be out of stock where I have looked. Not sure it makes a difference to anyone here. But just thought I'd post this info.
BTW, the .355" 147 gr. V-crown doesn't seem to be produced by Sierra.

The 124- and 125-grain bullets differ in an interesting way. The lighter 124-grain bullet is longer than its heavier 125-grain sibling. The nose shapes are different. The 124-grain bullet has a longer, more gradually tapered nose that would be typical of a 9mm Luger bullet. The 125-grain bullet has a shorter nose that is likely designed with the .357 SIG in mind, and it looks like the same bullet loaded in my sample of the company’s .357 SIG ammunition. SIG also loads a 125-grain bullet in its .38 Special, .38 Super and .357 Magnum ammunition.
