Dating my colt 1911
There could have been a shortage of military slides, and Colt used what they had by applying the M1911 logo to the commercial slides.
Many of these 1911's were reworked by the Government as well as gun smiths. First off the serial number is preceeded with a No and the o does have an underline.That's like the only thing I can think of to ask without having both in hand.The front site is different, the trigger, by the mag release, and the grip safety.I am interested in knowing the location of the Rampant Colt on the left side and serial numbers of 1911's that have this slide. Once I was able to upload my images, I posted several photos... All the best, Rob The double marked slides were not replacement slides, but were commercial slides diverted to the military contract in mid 1918. Hi BGold, Try looking at the following link to an older thread in this forum. It has a commercial and military marked slide on it.
