Not trying to hijack this thread, but as one who also recently purchased a Colt DA model 1909, I have been trying to learn more about this revolver's service history (printed info is sorely lacking). So apparently 20,500 guns went to the Philippines, while 1,000 stayed in the U.S.. My question is, when the troubles in the Philippine's finally ended in 1913, what happened to the 1909's? Were they returned to the U.S.? Is there any way of using a gun's serial # to "track" its movement in the Army? I'd like to find out whether or not any of the 1909's found there way into service with the Spruce Production Division's 1st Provisional Regiment. The Regiment's squadron leaders were issued Colt .38 and .45 caliber side arms, and a photo in Rod Crossley's book, "Soldiers in the Woods" clearly shows a revolver butt-forward in a model 1909 flap holster on his hip. I would think that the Army would have wanted its model 1917 revolvers at work in more "important" roles (for the lack of better term) so the model 1909's could have been used in the woods. Or am I completely off base, and the .45 Colt caliber 1909's were simply retired from service by 1918?
