Trigger Sear relationship Q??
My search foo may be off but I did try to find an answer before posting this so if it's out there a prod in the right direction would be great...
If not please share your vast knowledge.. I have seen and watched the LUGER Animation trying to understand exactly how the stricker is released.. While that did not help me too much my close visual inspection awhile ago did clear it up I THINK?? It looks to me like the TRIGGER bar pivots/moves on the PIN inside the SIDEPLATE.. When the TOGGLE is moved rearword it cocks the STRIKER assy behind the SEAR.. The TRIGGER moves the TRIGGER BAR thus pushing/tripping the SEAR and releasing said STRIKER... Is that pretty much it?? "IF" so what is the function of the little springloaded plunger doohicky that sticks out from the SEAR??:confused: TIA for the help...:cheers: |

The L-shaped bar inside the side plate can be considered to be trigger's extension. When trigger is pushed, the L-bar pushes down the spring loaded head of the sear to release the striker. "Bang". The barrel extension recoils, the sear goes along with it, and the L-bar does not control the sear anymore. Sear returns to its 'locking' position under the force of sear spring and locks the striker again. After everything returns to their 'normal' position, the head of the sear is blocked by the L-bar because the trigger is still in the 'pushed-down' state. The trigger must be released so the sear head could go under the L-bar again for the next shot. So, semi-auto.
One item might be interesting to think.... if design a "Schnellfeuer-Parabellum", what's the best implementation? Historically, there was full-auto version of Borchardt, recorded in John Walter's book. Not legal to build one, but on paper should be OK. |
Thank you Alvin...
O.K. so when/what does the DISCONECTOR play it's part and what does it do in this application? Please keep in mind I "DON"T" have a Sideplate (or it's parts) for my LUGER yet.. They were missing when I bought the gun.. It might be easy to understand where these parts in front of me so I am trying to figure this out kind of blindly.. The parts are inbound though and it may very well all make sense to me then? The TIGGER BAR is not spring loaded correct, if not is it returned to it's position by the Spring of the SEAR? |
The L-shaped trigger bar is not spring loaded, but the trigger is spring loaded, and the the shorter leg of the L-bar is inserted between the "sleeping U" at the tip of the trigger. When the trigger is released, it returns to its forward position under the force of the trigger spring, and trigger "sleeping U" pushes the shorter leg of L-bar up, so the longer leg of the L-bar goes outward, sear head (disconnector) now has empty space to return to its forward position under the L-bar's long leg again.
So, in this application, the trigger controls the sear via the disconnector. By turning disconnector "on" and "off", semi-auto was enforced -- you have to release the trigger to reset the disconnector to fire again. Pistol is like wristwatch. Every gear has been standardized, implemented in a little different ways, but virtually under the same principals. |
While I was composing my answer, Alvin explained the disconnector. My explanation is worded a little differently, so perhaps between the two you can visualize the function of the disconnector. Here is what I wrote:
DYNOMIKE. The disconnector is what permits the Luger to function as a semi-auto pistol. When you squeeze the trigger it presses down on the lower arm of the transfer lever (what Avin referrs to as the L-bar) which is located inside the side plate (which unfortunately you do not have). Pushing down on the lower arm causes the upper arm to rotate in, which in turn presses on the disconnector causing the sear bar to move and release the striker (firing pin). As the action returns to battery to fire the next shot, with the trigger still depressed the upper arm of the transfer lever is still in its innermost position. The disconnector contacts the transfer lever and, being spring loaded, retracts into the sear bar. Only when you release the trigger and allow the transfer bar to rotate back out can the disconnector "pop out" and be in the firing position again. |
Thank you gents, I appreciate the time and replies..
I think I have a pretty good understanding now & it all makes much better sense to me.. |
Dynomike,
where do you live in South Florida ? I could show you how it all works with a complete functioning Luger if your interested I live near West Plam Beach Jim |
Hi Jim~
Actually pretty close, I'm a touch North in St Lucie County.. Could make that trip easily, maybe next month when I come down for the FUNSHOW at the FAIRGROUNDS?? I hope to have my parts towards the end of this week and am keeping my fingers crossed she runs fine at that point?.. It would be good to have some help though if needed as WPB is only 45 Min for me.. Thanks, MIKE |
Mike,
I'm in Stuart, so were real close, we could meet at my work if you like. Send me a pvt e-mail to and we can set-up the details. I'm sure we can get the Luger to function correctly jamesegg@bellsouth.net Jim |
Thank you Jim~
E-mail In-bound.... MIKE |
