Luger Trigger Help?

OK, basic problem is that my Luger fires and cycles just fine, but the trigger does not reset for the next shot. The trigger and firing pin do reset when the toggle is run manually. I have gotten some info from the Lugerforum, but that hasn't fixed the problem.
Anyone here feelin' my pain and can offer some advice?
Thanks.

I have limited experience with lugers,:uhoh: but was looking at mine and it would be hard to diagnose without pics, and I'm not familiar with the terminology of this pistol.:confused: That being said, soo many parts are responsible for the cocking and release of firing pin!:eek: It's an intricate process that only requires the bolt to move about 3/8". First thing to do is disassemble and clean/flush then lube and reassemble. :scrutiny: Check spring behind trigger, check that the side-plate is properly fitted, it houses the lever that begins the process of releasing the firing pin. Likely problem is that the plunger tip that is contacted by the lever in the side-plate is stuck in position. This plunger tip must be able to move freely in/out. This doesn't fix your issue then we dig deeper. Pic shows pen cap pointing to plunger tip, and the pen is pointing to the lever that contacts this piece and that is actuated by trigger.;)

I did the trigger lever/disconnector pin modification, got that info from the Lugerforum. It didn't fix the problem. The firing pin cocks when cycled by hand, and it releases without a problem. Seems to be a problem in the trigger system.

Can you get some decent pics of your gun to display? Are you comfortable in breaking it down? If your is the same style as mine we should be able to diagnose the issue.
The trigger system is what we already covered, not much to it. Just need to make sure the parts are clean and in good working order. Next thing to look at is the disconnect and firing pin. Tomorrow I'll try to get some pics of mine up and the various steps of break down.

Break-down is not a problem, I've had most of it apart. I have improved trigger lever functioning with a slight bevel and a new, tight fitting pin. I did the bevel edge on the disconnector pin. All the parts are moving freely and spring tension seems fine, to me. Everything is clean and lubed. It cycles fine by hand, just not after firing.

If you let the toggle go forward under full spring pressure it cocks the firing pin, but wont after firing a round? Or do you have to ride the toggle forward slowly and actually push it down into full battery to cock the firing pin? Maybe the disconnect spring has lost some tension and isn't keeping the disconnect in place long enough to catch the sear located on the side of the firing pin. Or the trigger lever is preloading the disconnect so as to prevent the mating surface of the disconnect from catching the sear and cocking as toggle comes down and bolt moves into battery. Whatever it is, there isn't enough surface area of the sear being caught by the disconnect under firing, it's just passing by the disconnect as the bolt goes into battery. Remember these guns were hand fitted, parts numbered for a reason, they work great if kept original, start replacing parts and then the hand fitting comes back into play. When pulling the toggle back to cock the weapon, you should hear an audible "click" as the sear is pushing the disconnect outward while the two mating surfaces pass. You will see the disconnect pivot outward from the frame at the point where the safety would engage the side of the disconnect. Also check the fit of the side plate, it should fit flush to the frame on all edges without effort. If the side plate isn't fitted properly then it's preloading the disconnect.
Any way to post pics?
