Useful to know what pistol you have as well. Loading the 9MM is akin to loading rifle. The 1:10 twist that most pistols come with is not the best twist for accuracy but works. Depending on the pistol platform you can get replacement barrels with 1:16 twists which is probably a better barrel twist for the 9MM.
I prefer the 124/125 gr bullets personally in the 9MM. Overall I think they are a better option for the 9MM for accuracy.
