Finally, my first Luger

One style for pinching, one style for snagging with hooked fingers!

I just checked my M1900's toggle knobs against those on a P.08.

Measuring across the top of each pistol:

Overall width 1900 toggle at extremes = ~1.56"

Overall width 1900 toggle at minimum = ~1.30"

Overall width P/08 toggle........................~1.42"

Knurling characteristics of 1900 toggle:
Serrations/groove applied radially to the axis on its rounded front corners, a bit more than 180 degrees. I guess the grooves are also concentric with the radius of the rounding on the front corner.

Knurling characteristics of P.08 toggle:
The edges of the knob's faces are not as rounded as the 1900, more like chamfered at an angle. Serrations are applied to the chamfered edges in radial fashion, as well as applied on the outer circumference, parallel to axis. The former go all the way around the circumference and the latter go most of the way around, skipping the part which bumps into the frame's ramps. The knob's face is checkered and flat.

Looking at this data, my deduction is that whether original or copy, this rear toggle is probably not a converted P.08 toggle. One can confirm by measuring, and also by the 1900-style of knurled texture that this is a 1900 toggle with the accommodation for the toggle lock filled in, and a hole drilled for the axle retention pin. Easier to fill in an original or make a repro?

To make a faithful recreation of a 1900 part from a P.08 part would require removing all serrations entirely, as well as building up the front of the knob, dishing it with a mill (ala' our fine sheepherder), and re-serrating to the earlier specs.

May be a 1900 that had the slot filled and pin added to "work" with a P 08 type frame?

The milling of the grooves is not consistent with a cut out P 08 toggle; like this one Rich did for me. Scallops are not as "deep" since the toggle is not as wide.

I just like the "dished" look.

A quick measurement, compared to Dave's data will tell the tale.

Thanks for all the great info! I closely examined the inside of the right toggle and think I could barely make out where the toggle hold slot was filled. I don't think I'd really be able to get that in a picture. I'm going to take some measurements as soon as I find my darned calipers. Once I get those numbers I'll post them.

So how does it shoot?
