Is there any difference between a

.38 SUPER COLT 1911 Government Series 80 barrel

and a

.38 SUPER COLT MK IV Series 70 Government barrel ?

Can they be swapped ?

  Probably.
  I had a 1954 Super 38 with a Series 70 barrel in it. Worked fine.

  The Series 70 barrel will have a bulge in it near the muzzle for the spring-finger bushing that was used. Need to make sure the bushing you use will locate the barrel without binding it in operation.

  I want to replace a Series 70 barrel with a bulge near the muzzle and the spring-finger bushing with a Series 80 barrel.
  
  Brownells has a large selection of barrel bushings, what would you recommend ?

  You need to match the bushing To the diameter of the barrel . For this You need to mic the barrel and then order a bushing. Be aware the barrel tips down at the back so a one thousands clearance will bind as the barrel tips down . There is one bushing that has a Floating Ball
  within the bushing this prevents binding as the slide cycles . In my opinion the stock series 70 takes in to account this with the spring finger Bushing. Again unless you have fitted a barrel to slide and barrel to bushing before and have the knowledge and tools to fit barrel hood /locking lugs / Slide stop/ barrel link/ and bushing most likely you may end up with a pistol that shoots worst than the one that you have with stock parts. I don't want to throw cold water on your project
  just trying to give you some food for thought. "PRAISE THE HARD-BALL GUN " Karl AKA PERRY SHOOTER

  I just got my new .38 Super barrel from BarSto and it came with a nice fitted bushing. The only thing I had to do was some light stoning on the hood for perfect fit. I have used their barrels for years and highly recommend them. Their Super barrels are set up to headspace on the case mouth for better alignment.

  YES!!!!! They are to the same spec. Lock up will be the same. The only difference is the series 70 has the barrel under cut .800 behind the muzzle to a diameter of .472 on the series 70 while the muzzel is the standard .579 +/-. If you have the non fat barrel you will need a bushing to match that.
