Since the 38 Super is longer than the 9mm, I don't think the magazines are interchangeable.
I think Springfield puts ramped barrels in the all 9mm's but not the .45's. It's really not needed in the .45 anyway.not sure about the new Range Officers?
but mine a 45 has non ramped barrel, a very adequate recoil spring and all and all the weapon is very well built and finished.
its actually my most accurate 1911.
9 MM PSI=35,000
9MM plus P 38,500.
38 super 36, 500 PSI
that's of course SAAMI rates, as mentioned factory 38 Super is likely not at the top as the 9 MM is the same generally under the rated pressure, which I am sure you already know.
Normally, a 9mm magazine in a 1911 just has a spacer in the .38 Super magazine. Other than that, just have the barrel reamed, or rechambered for the .38 Super and it should run. Ramped, or not, the gun should run fine with just the barrel being rechambered for the .38 Super.
Recoil spring change could be determined later as you tune the gun. Same with the extractor, it should not be a problem, but the .38 Super was originally a semi-rimmed case.
9mm and .38 Super (Plus P) run about the same pressures, so that won't be an issue.
MY Springfield Armory Micro Compact 1911 in 45 acp has a ramped barrel, the Range Officer as mentioned does not.I think Springfield puts ramped barrels in the all 9mm's but not the .45's. It's really not needed in the .45 anyway.
.I would like to be able to switch back and forth from 9mm and .38 super if I want so I will not ream the factory barrel but I will either buy new .38 super barrel or another 9mm barrel from Springfield and have it reamed. Thanks everyone for your help.
Just curious but why the .38 Super and not the 9x23 Winchester?
Personally, I might consider going to the 7.62x25 before either of those two.
Very nice looking pistolRegardless I love my 38 Super. It is a Kimber Pro Carry HD II.
