Richard,
Not wishing to be picky, but your frame to grip strap obtuse angle should be over 90 degrees. Perhaps the 74 degrees is an acute angle on the flip side of the grip strap line.
Have a very Happy New Year.

You are both correct; I could not find a right-hand pic online with a white background. The angle is correct (for my Gov't Model) just on the wrong side. It's now corrected.

BTW: FWIW, the pic I had up originally, of an after-market frame being milled, only measured 72 1/2º. I had another one lying nearby; that one was also 72 1/2º. Only my Colt actually measured 74º. The 1928 blueprint I go by did not have a direct degree measurement. I had the Colt broken down for comparison. The print seems genuine, but some of the measurements are very strange. Like, just what fraction in inch or Metric is .110"??? And why would anyone bore a hole 29/64"???

After the successful testing of the Colt Model 1909, John Browning designed the .45 Caliber Prototype 1910. This prototype was a result of complementary praise by the Ordnance Board of the Luger anatomical features. This prototype has a slant grip for more natural grip and natural point. Browning demonstrated and tested the .45 Caliber Prototype 1910 at Fort Meyer in February of 1910. This prototype was the predecessor of the Colt Model 1911 Government Model.

[QUOTE=sheepherder;311981]Hmmmm,...Lessee...Yep, I get 74º on a Colt Gov't Model frame...(Measured on the front gripstrap)...

Thanks to John for pointing that out!

FWIK the 1911 grip angle should be 118 degrees.

It depends on which side of the angle you measure. The 118 +/- degrees is the compliment of 74 +/- degrees. Added together they make 180 degrees, i.e. the straight horizontal line that the grip angle is measured from...118 degrees on the trigger guard side, 74 degrees on the grip side.

You got your quote screwed up. I'm sheepherder; he's luger.parabellum.

Here's some food for thought...Pic of blueprint attached...

90º minus 17º 30' = 72º 30'...(72 1/2 degrees)...
