I was contemplating making a humorous comment like "those 5 or 6 hole thingys in the drum" but quickly realized that it would rightly scandalize members with gravitas who are deadly serious about terminology. So, my sophomoric contribution is why not use standard gun terminology that has been around for centuries? Breech is the term that describes that rear part of a gun where cartridges are loaded. I know it is typically used on rifles but it doesn't have to be exclusive to rifles as the definition is broad enough to encompass handguns as well.
Ok, that's my contribution. Let the beating begin...
