					The Colt Model 1900 in caliber .38 ACP 
					(Automatic Colt Pistol) was the first of a long line of John 
					Browning designed semi-automatic pistols that were both 
					licensed and manufactured by Colt’s Patent Fire Arms 
					Manufacturing Company in Hartford, Connecticut.  Some 
					collectors refer to the Model 1900 as the “Colt Paterson of 
					semi-automatic pistols” since Colt’s original Paterson 
					Model revolver was manufactured by Sam Colt in Paterson, 
					New Jersey and first offered in 1836.  
					Collectors tend to categorize the Model 
					1900 into two distinct variations 1) sight safety models and 
					2) sight safety altered models.   
					The earliest pistols were manufactured 
					with a unique firing pin block safety.  With the hammer 
					cocked and sight safety lowered, the sight safety served as 
					a firing pin block.  When raised in the upper position, the 
					device also functioned as a sight.  This sight safety and 
					the hammer have a similar appearance as both have a color 
					case hardened finish.  (this finish may no longer be present 
					on examples that have considerable wear of have been 
					refinished.) 
					At a point in production, Colt’s 
					decided to abandon the sight safety and offered to alter any 
					existing examples by removing the sight safety and replacing 
					the device with a plug that was pinned in place.  Often 
					these altered examples were also refinished by Colt’s at the 
					time the alteration to the safety was performed.  Examples 
					of the Model 1900 that were manufactured after the decision 
					to eliminate the sight safety left the factory in a sight 
					safety altered state. 
					The Model 1900 was manufactured for 
					three years with a total production of just under 4,300 
					pistols.  Some of the more interesting variations are those 
					that were purchased under contract for the U.S.  Army and 
					U.S. Navy.
