[Ron Wood]

Presumably as a cost cutting measures, the Army elected to eliminate the stock lug that the Navy had adapted, the grip safety, and the hold open. Until the LP08 came along, there was no need for the stock lug, so that was a logical choice for elimination. The grip safety was actually redundant (cavalry troops might argue to the contrary) so it too met a well-deserved demise as a military necessity. However, not knowing when your weapon was empty in a heated disagreement proved to be an embarrassment of significant proportion. So in 1913, sanity reared its head and the hold open was once again recognized for its vital role and returned to its rightful place in the military Luger, where it remained until the end.
