    Sistema Colt

    Are Sistema Colts made in the late 50's of the same metallurgical quality as Hartford 1911's?

    Have no idea about metallurgy of the 1950's era Sistema, but by that time The Colt Government Model was using a hardened slide. The Model 1911 had no tempering at all in the slide and receiver.

    Well, since they were produced in Argentina from 1927 to 1966, they must have been made to 1911 specifications.

    When did the hardened slide come along for the government model?

    The hardened slide was experimented with during the last days of WWII, and each manufacturer sent samples of hardened slides to Springfield Armory for testing. Production of the 1911A1 ended before the hardened slide was made standard, but Colt quickly transitioned to the hard slide for the Government Model. The steel used in the Model 1911 was not the same as used in the Model 1911A1, but I have no idea about the standards used in the Sistema.

    Beginning with 1937 production the Model 1911A1 slide was hardened at the front, and in 1943 the slide stop notch was hardened. These areas can normally be seen as slightly darker than the rest of the slide.

    I think the key word here is "transitioned". I wondered how long colt used leftover parts of ww2 vintage. Would it be safe to say that by 1948 that these ww2 components were used up? I am not sure, I would like to know if there is a definite date.

    This Government Model was shipped December 17, 1946, and all parts appear to be GI with the exception of the receiver. Of course the receiver could have been in a state of completion where it had not received any identifying marks, but it cannot be identified as such.

    From Xavier's site, "...with the first ten thousand built by Colt in Argentina for the Argentine Army. Colt equipment and employees were relocated and the manufacturing began. From 1927 to 1933 ten thousand pistols, known to collectors as Hartford Argentine Army Models were produced." This is FALSE........ the first 10,000 Colt's to fulfill this order were manufactured in Hartford, CT.... hence the "Hartford" part of the name..... They were produces from July 1927 to February 1928...... Afterwards, the SISTEMA COLT were produce in Argentina..........

    It's a shame when someone has a bit of incorrect info in a post or article, because it brings all of what they offer into question. SCone is right, the 1927-1933 Hartford Colts were built for Argentina in the USA.

    So, what is the advantage of the post-WW2 hardened slide? Does it make the firearm last longer?

    The Model 1911A1 slides had the front end as well as the slide stop notch hardened to prevent wear and peening in this area, plus the slides had a hardened steel insert in the breech face. The fully hardened slide took care of all of this as well as wore better when fitted to a receiver.
