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! :thumbup:


FWIK the 1911 grip angle should be 118 degrees.

[QUOTE=luger.parabellum;312009]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. :rolleyes:

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

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

Yeah Richard, I messed up when I omitted parts of his post but didn't go far enough to eliminate the reference to your alias...I apologize for the apparent misquote.
Your food for thought is indeed interesting. Odd that the blueprint spec matches your aftermarket frame but not the original Colt frame.

Ron, I have several copies/sets of 1911 blueprints, from Dept of the Army Rock Island Arsenal, Dept of the Army Springfield Arsenal, and from US Armament Research & Development Command, Dover New Jersey. They have mixed dates on the prints within the sets, some are marked revisions, some not. There's 1928 dates, 1936, even a 1960. I stopped checking. :rolleyes:

In addition, I imagine Colt made numerous changes to their Government Model over the years. The grip angle may have been one of them. :confused:

[QUOTE=Ron Wood;312014]Of course 118 degrees is measured at the trigger guard side.
