The hole in the upper right of the mainspring housing.
I know it is .0?15 Dia.
Can someone measure it for me?
Thanks in advance..



Part 2
This number is impossible to read can someone measure it with calipers or a Mic?
Thanks again
Top most back edge to front of slide..
The number I think it is .166 or .168 but I could be way off.

Don't have a set of pins, but a 0.078 (measured) drill rod is a nice sliding fit.

0.136

A little hard to measure with a caliper, but there's no way the part that I have (from a GCNM) could be .166

That is possible. Could be .136 + - .002
This is what the image looks like

According to Volume 2 of Kuhnhausen's book, ordnance spec for the small hole diameter is 0.0845 + 0.001 and the pin diameter is 0.0845 - 0.0015. For the large hole the diameter is 0.280 + .005 and the mainspring cap dia is 0.279 - .002 (see pages 166 - 167).

Hope this helps-
