Are you referring to the one right above the chamber on the end of the barrel? half moon shaped looking protuberance? If so that part coincides with a half moon shaped recess in the top of the breach face and provides clearance for the case rim when the barrel locks up, preventing the case from being crushed by the chamber. If you drop a round in the chamber of the barrel when removed, you will see that the "tit" is roughly even with the primer face of the case.

This thread has to be on the verge of getting way outta hand, I can't be the only one holding back on dirty immature comments!

Early Tanfoglios had them, now they don't; they seem to work fine without...

I thought this was the purpose of it but my 40 barrel is either short chambered or it isnt the purpose because my 40 case sticks out past it.

I read somewhere awhile back that is is to enhance feeding of hollowpoints.
