In 96%++ very sharp original un-messed with condition, we have a US Army Colt 1924 Transition Model Pistol, the very first production of what would be soon known as the Model 1911a1 Pistol. Initially called the “improved model 1911“, the nomenclature was changed to Model 1911a1 in May of 1926. Today, collectors refer to this pistol as the 1924 Transition Model. There were 10,000 of these pistols produced and this one was made in the middle of the run and was shipped out to Springfield Armory in July, 1924.. This pistol is factory original and totally correct as per Clawson and it does have the HP marked barrel and the bore is mint. Most of these pistols were lost during WW2 or rebuilt after the war so this is a real find. Colt made 400,000 pistols during the second World War and only 10,000 of this model 1924 Transition were ever made, so this is an incredibly tough gun to locate, especially this crisp.
