Toggle link question?
 

I have been curious about how much difference, if any, are the dimensons between the 1900 lugers and the later lugers. I have been just looking at mine and its obvious the difference with the front portion of the toggle that holds the fireing pin. But what about the middle link and rear link. I took some dial calipers and measured them both and they appeared to be very close in size. But my measureing aint exactly the best, so I figured Id ask the question and see what the real answer is.

Glenn,

Generally, the 1900's would be "old model"--with a frame that is around 1/8" longer than a P.08. I think the difference is made up in the breech block. The change from long frame to "new model" happened--I think-- around 1906, but you better look it up to be certain. I have two 1906 AEs, one is long frame, the other short.

I see were there are some blueprint disc on one of these threads for sale. I wonder if it has deminsions for both styles. I have a 1900 AE and the breechblock is very obvious difference between my 1917. I was shooting my 1917 the other day and when I was cleaning I was just checking it out and seeing if the rear part of the toggle could be interchanglable if one desired. My 1900 resr link has some small indications in it and I know that shooting it anymore with it in wouldnt be wise.

The Bluepirnt CD contains only the military blueprints for the P.08 model with the 4 inch barrel. I do not have the blueprints for the long frame model, but do believe as stated previously in this thread that difference is made up in the breechblock... the rear toggle of both types is likely the same length.

For those interested in obtaining a copy of the P.08 blueprints... see the "sticky" thread at the top of the "for Sale" forum... (http://forum.lugerforum.com/showthread.php?t=11286) Still only $25.00 USD. And now available immediately by download instead of by mail... a real interesting "read" for those who admire Luger engineering...

Thank you Mr. Sabato. I know measuring it physically it didnt seem to have much difference in size down to the 0.005" plus or minus on my dimensions between the two. But I was just curious what others thought as well.

The difference between a "long frame" and a "short frame" is all in front of the takedown lever. From there on back they are close enough to dimensionally the same that parts are just about interchangeable (perhaps with a little fiddleing). I married up a 1900 rear toggle link with a 1906 forward toggle link and breechblock and installed them in a 1900 receiver. I had to open up the extractor notch in the receiver and barrel to accept the new model extractor, but everything else went together well.

As Ron stated above, the overall toggle dimentions are about the same. The dimentional difference between long & short frame is in the receiver (barrel extention), which is an 1/8" longer in the theaded area. THe M1900 mid toggle link may look similar to a later DWM PO8 link, but the angle of the cocking arm is different and thicker, so that only the flat surface of the M1900 FP will work with it. A standard round PO8 FP will not pass it. Finally, to use a standard rear toggle link in a M1900, your will have to use the shorter M1900 "S" shaped connecting (to the flat main spring) link, or the toggle will not open fully. TH

So I'd say if I was to switch any part of the toggle out just so I could shoot the 1900, I'd better stick with a 1900 style toggle. I goota asve some money on that one. I love shooting the old style 1900's luger I have and I will not shoot it again after finding the small linear indications in the rear toggle. But eventually I do want to change it out and get it shooting again.

Thanks for ya'lls opinion on the dimensions on these parts. I was trying to think out the box and use some parts that are available local really cheap from some of the later version lugers.
