Chamber ridge

AGE · 01-16-2003, 11:36 PM

Guys,

I shot both of my Lugers that have the chamber grooves today. John was right, there is a very slight ridge around the fired brass. I never noticed this because I don't reload 9 mm, I just use cheap Wallymart bulk pack ammo.

I once had a .38 Special Colt Gold Cup that had grooves all along the chamber wall to retard slide opening of this blowback design until the chamber pressure dropped. It really screwed up the finish of the cases, but it worked fine. Do you suppose there is a functional reason for the Luger chamber groove?
