Colt 1905 45acp

Practically a museum piece. There can't be many of these around in this condition w/box. I believe better, brighter pictures would have brought more money.

The original Colt 45 Automatic Model 1905 cartridge used a 200 gr round nose jacket bullet and even after the Model 1911 and
230 gr jacket were introduced, the Model 1905 45 automatic remained in production to around 1925

The original Colt 45 Automatic Model 1905 cartridge used a 200 gr round nose jacket bullet . . . . . .

I was wondering if someone would pick up on this point!

Apparently it was little-known, back in the day, that the ‘05 needed 200 gr. bullets. . . .not 230’s.

Hence we see a lot of cracked slides . . . .mostly at the forward link . . .of these pistols.

Same thing with the early Colt Model of 1900 and Model 1902 Military Model using the 38 Colt Automatic cartridge. this
cartridge was an excellent design and superior to the 9mm in energy but the military was not interested and the Police
Departments preferred revolvers. These models were discontinued in 1928 (model 1903)

Colt brought out the 38 Super cartridge in 1928 with the modified Model 1911 using the same 130 gr bullet at 1300 fps.

The new 38 Super was considered too powerful for the older Colt automatics yet both cartridges appear identical

When initially introduced the Colt .38 Auto cartridge was loaded to 1260 fps out of the 6" barrel. At various times the cartridge was loaded to 1160 to 1280 fps for the Model 1900.

When the Colt Super .38 pistol came out in 1929 the cartridges were initially the same as the Model 1900 cartridge, and were 1190 fps out of the 5" barrel. In 1932 Remington came out with the .38 Super cartridge loaded to 1300 fps out of the Colt Super .38. In later years the .38 Auto cartridge was loaded in brass cases and the .38 Super in nickel plated cases to help differentiate the two cartridges. Today the .38 Super cartridge is designated as a +P to denote that it shouldn't be fired in one of the early Colt .38 Autos.

It was said years ago by Charles Suydam, that perhaps Colt should have made the 38 Super just a little longer so as not to chamber
in the 38 Colt pistols
