Cam Peening
Kenyon (Lugers at Random) page 296 shows a Mauser Prototype: â??... the cam ramps are slightly peened from the continued action of the toggle knobs.â? This also happened to my first DWM Luger. Eventually, the receiver started to bind within the frame. I had to carefully remove the excess metal from the inside of the cam ramps with a whetstone. The DWM and Mauser production tables (printed in G?¶rtz: Die Pistole 08) show that metallurgy had progressed during WWI by the time Mauser started production. I had also been using commercial ammunition with too high a charge. Patrick
