Help with my toggle catch?

[John Sabato]

To remove the holdopen, you simply lift the rear end up high enough to pull it to the rear so that the spring slides out of its slot. Easy.

This is a perfect example of why Lugers were hand fitted and all the parts numbered. Look at the top of the safety bar in the same photo. See how tight the clearance is on that part and the rectangular hole it rides in? The level of precision engineering necessary to manufacture this pistol never ceases to amaze me.
