Is .32 S&W Long Ammunition Compatible with Smith & Wesson .32-20 Revolvers?
Question can .32 s&w long ammunition be fired in a Smith & Wesson .32-20 revolver?
Answer Sorry, but no. With a S&W .32-20 revolver, you should not fire a .32 S&W or a .32 S&W long (or .32 Colt) cartridge. Those cartridges have a smaller diameter at the base, and can ruptire on firing. Such rupturing may injure the shooter or others.
