The .32 acp will fit in a .32 Long chamber, and it is semi-rimmed. BUT, they do work at a higher pressure and it is not advisable to use them in a .32 long. .32 S&W Long is readily available from many internet sources such as Midway and Brownells, as well as most larger gun stores. It is not overly prices as 38 S&W is. It is also easily reloaded. It is a very accurate round with very little recoil. We would need to more accurately identify your gun before recommending shooting anything in it.
