.355 diameter 357 Sig MG 125 gr JHP for 9mm

Running low on the Montana Gold 124 JHP I usually use, can I use 357 Sig bullets that are a .355 diameter for minor 9mm loads? This is for a Glock 34. Anyone tried this? What adjustments did you make?

I have been using them for a while now. The nose of the bullet is slightly more abrupt and the bullet body is longer than the 124 HP so I had to adjust my OAL shorter and reduce my powder charge somewhat. It is because of these that I sent my barrels out to Springer to get them throated so I could at least load them back out to 1.125. They shoot great!

Thanks for the replies. I was able to get some 124 Gr. Montana Golds direct and also some more on Gun broker. Should be all set now.Good to know the Sig bullets are an option if needed.
