Yes but 99% of the time you will be required to have a different caliber for you handgun due to scoring.

Are you asking about IPSC (3 Gun)
USPSA (Multi Gun)

Depends on who is holding the course. The three I've run have stated rifle calibre for the rifle portion of the course (223, 308 7.62x39, etc).
