floriosean1, I have a J&G sales 1911 conversion kit for shooting 7.62 X 25 Tokarev. The kit contains a barrel and a bushing. rest is up to you. you need 38 super magazines and a 9mm or 38 super 1911 (needs a feed ramp) The kit works to a limit. If you are reloading the ammo, you will get rid of the two main bugbears of this conversion.
1st is 7.62 X 25 OAL is longer than 38 super. normally you can load only 5 rounds before the angle of the cartridge in the magazine causes a jam. If you reduce OAL while reloading, you can get more rounds in the magazine.
2nd is the issue of hard primers. Because of surplus ammo, you require a higher rate hammer spring.
Another issue I have found is if you need to eject a live round, you have to drop the magazine to allow the live round to slide down the magwell as the ejection port is too short to allow a live round through.
In case you want to know more or handle a conversion, let me know, I am not too far from you (whitby). PM me.
