Colt Model 1900 Sight Safety Serial Number 1690,
Army Contract - The Colt Model 1900 is the first
Browning designed automatic pistol model licensed to and
manufactured by Colt Patent Fire Arms Manufacturing Company.
This pistol was manufactured in 1901, the second year of
production and is the second variation of the Model 1900
with forward plunge milled serrations, high polish blue, fire
blued small parts and course checkered walnut grips.
The Second Army
Contract pistol variation was shipped with the sight safety
intact, checked walnut grips, forward plunge milled slide serrations
and is identified by the "U.S." mark stamped on the upper
left flat of the trigger guard and "R.A.C." for Rinaldo A.
Carr (a civilian ordnance employee) on the upper right flat
of the trigger guard.
The two distinct features that differentiate the Second
Army contract from the First are the the course checkered
walnut grips and the forward slide serrations. These
slight changes were quickly implemented by Colt's in
response to some of the criticisms of the First Army
contract pistol. The grips were made larger and
checkered to minimize the gun twisting in the hand and also
to reduce the likelihood of the gun being dropped. The
slide serrations were moved forward so the hand would not
interfere with the sight safety.
This serial number range for this contract included guns in
the serial number range from 1501 to 1700 and they were
shipped from December 28, 1900 to February 4, 1901.
