Heinz, the earlier Lugers were made on a "long" frame which is physically longer than the later "short" frame. The difference is not much but there is a difference. In profile, the two frames will be slightly different just in front of, and above, the trigger guard. The long frame has a more graceful and less severe curve to it. The short frame will appear to be more "squared". Production of the long and short frames actually overlap depending upon who ordered what. The slides will also vary in length according to what frame they were to be used on.

The sear or "trigger bar" on earlier pistols were cut so that the safety, if activated, prevented the action from being opened because the bar would strike the safety and prevent the action from moving far enough rearward to open. Later guns were made with a "relieved" bar that permitted the action to be opened when the safety was applied. Many of the earlier guns were also modified in this manner. It was a simple matter to mill the trigger bar back further.

Rick, the long frame slide is approximately 5/64 of an inch longer than the short frame receiver with the entire difference being in the length of the receiver ring from the face of the breechblock forward. The toggle train should be the same in both the long and short frames. This is according to "Lugers At Ramdom" by Charles Kenyon, page 23.

Wes, thanks for the tip. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

The toggle train parts are the same, but the barrels are not interchangable, the long frame bbls have a longer threaded portion. [img]cool.gif[/img]

Most long frame lugers, including the Swiss and Mauser Parabellum, were made with a grip safety, which has a sear that is cut in the opposite angle to the standard relieved or unrelieved trigger bar. I have plenty of this type available if needed.

I think I read in Fred A. Datig's book from the 1950's that all long framed lugers have a 4-groove barrel twist and all short frame lugers have a 6-groove barrel twist.

This was info. based in the 1950's....

Is this still considered "true" ?

Regards,

Pete

Gentlemen, Thank you all for your assistance. I I now know why the togle on my 1915 will not crank open when the safety is on and the .30 cal post WWI commercial I had years ago would. I thought I was just remembering wrong.

Thanks on both questions, Heinz
