Hi Bruce,
I try not to dry fire any of my lugers.
If the gun is cocked AND WITHOUT a round in the chamber, it can be un-cocked by pulling the toggle back only 1/2" or so and then pulling the trigger.
I also got some "dummy rounds" in 9 mm and .30 cal. that Brownells sold. These are bullets of the right weight of a regular bullet that can be cycled in the lugers magazine and through an entire extraction/ejection cycle and can be dry-fired at well. No powder in the casing and no primer...but the same weight/mass as a real bullet.
Last time I was on the Brownells' web site, they still offered the 9 mm but stopped carrying the .30 dummy round...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
