The old 32-20 cartridge is a bit of a light weight in its original loading. 218 bee and 22 hornet are also a bit light. 204 ruger would seem marginal to me also. Any of the .17 caliber cartridges.
Any service-size handgun cartridge coming out of a carbine/rifle length barrel is going to be a good self defense choice. 9mm, 40 S&W, 357 mag, 45 ACP, 44-40, etc...
