In the end, the “greatest” cartridge depends upon particular person wants and priorities. Shooters in search of most energy and potential looking purposes might discover the 10mm Auto to be the higher selection. These prioritizing concealability, larger journal capability, and simpler dealing with might lean in the direction of the .40 S&W. Each cartridges have their strengths and weaknesses and are well-liked for a motive.
