My understanding is that Springfield Armory GI and Mil-Spec models have 2-piece barrels. I know these pistols are extremely popular, but what, if any, should my concerns be concerning 2-piece barrels? I have a good friend at work who wants a 5" stainless or nickel or chrome 1911 and doesn't want to spend more than about $600. I have tentatively recommended the GI or Mil-Spec, but would like to inform him correctly regarding the 2-piece barrels. If he decided it was not what he wanted, would it be expensive (How much?) to replace it with a one piece barrel. How much fitting would be required? Any suggestions or recommendations regarding alternate solutions? Wanna kill these ads? We can help!
