    I was watching a video earlier, and in it they were talking about barrel swaps. (10mm to 40 S&W). This made me curious.

    If I wanted to do something like change my 45 ACP into something based off the 45ACP casing, would all I have to do is change the barrel? I read that .400 Cor Bon is basically a 45 ACP shell necked down to .40 caliber. Would that round work in a 1911 if I just changed the barrel?

    What other rounds could work?

    This is mostly out of curiosity. I don't plan on doing this for at least a while.

    One more question. I think the .400 Cor Bon has a higher pressure than a 45 ACP. Would they be too hard on the gun?

    I know that several makers sell a 460 Rowland conversion kit. It is kind of like a 45 acp mag. Sort of. Canebrake has one that he has talked about before. Perhaps he can point you in the right direction.

    I don't think he's been on in a while. :(

    460 Rowland? Sounds interesting, but can a regular 1911 handle that?

    Yes. They say on the website that any quality 1911 can be used. They don't recommend using RIA or low end guns. Let me see if I can remember the website.

    Here is a link to one of the websites.

    http://www.clarkcustomguns.com/rowland.htm

    Apparently Buffalo Bore makes 460 Rowland ammo that shoots a 255 grain bullet at 1300 fps.

    That is getting close to 44 mag performance. Hodgdon shows 44 mag loads at 240 grain bullet at 1250 - 1582 fps depending on which powder you use.

    The 460 Rowland is a serious round.

    What about the .50 G I?
    Doesn't that use a .45ACP slide?

    Guns with a .45ACP breechface could be converted to other calibers with a similar case head size, 400 CorBon, 460 Rowland, 38-45,etc. The .50 GI apparently uses the .45ACP sized case head, but I believe requires a bull/ bushingless barrel and other changes due to the physical size and greater recoil impulse of the .50 GI cartridge. On this one, I wonder if magwell dimensions had to be increased due to the larger cartridge/magazines?

    Pistols with the .40/10MM breech face can also handle conversions to .38 Super, 9X23MM, 9X19MM, .30 Luger,.357 SIG,etc. I've thought about doing some of these myself on some guns with the .40/10MM breech face, but only got around to 9mm,9X23MM and .38 Super. All accomplshed with very little effort, and minimal tuning. As always, the devil is in the details and different magazines will be needed with some conversions, along with recoil spring, extractor,ejector,etc. tuning. Many things are possible with the 1911 platform...ymmv

    Colt, SA, and a few others are recommended for the .460 rowland. None of the RIA guns are to be used. Seems Colt is the one most use. And yes it is a bad arse gun.

    They recommend that you do not put that kit in a rimington r1, your going to blow yourself up. The pistol needs to have been heat treated, that's why they recommend higher quantity brands

    They specifically name the Remington 1911 R1 as one of the guns that this conversion is for though. :confused:

    I saw that they said not to use a Remington Rand 1911 though.

    Remington and Remington Rand are not the same company nor are they related in any way. Remington did make some 1911's during WWI. Remington Rand was an office machine maker that made 1911's during WWII. so the Remington company hasn't made a 1911 since the end of WWI.

    Not sure. If I end up doing that, I will definitely talk to them first.

    Interesting. Thanks for the info. :)

    the one thing about the Rock Island 1911's is no matter if it's a 22 tcm, 9mm, 38 super, or 45 acp; they all use the same size barrel bushing. pretty much just switch recoil springs & magazines with the barrels.

    of course this only applies to going smaller than the 45....and probably only with Rock Island's guns but it's food for thought
