Gentlemen,

We have discussed the Luger's stepped chamber on this forum many times. The experts here have agreed that the design was originally intended to assist in gas sealing the 9mm chamber, due to the original powder available and used by D.W.M, at that time.

It is very interesting to me that newer designed firearms would copy such a design.

As noted above, original 9mm Luger military and civilian ammo was loaded out rather longly, as was their 8mm Mauser ammo as well.

Proper O.A.L. Luger ammo, as noted above, may be just too long to chamber in more modern designs, as round nose rounds can range between 1.169 and 1.173 inches.

As to maximum accuracy, in both rifle and pistol shooting, I have found that a bullet, just kissing the lands, to be the most accurate.

Respectfully,

Sieger
