keep an eye on gunbroker, IIRC there was a complete 455 1911 on there recently (past month or so) or at least the parts from one...Josey said:I am interested in putting together a WWII English 455 1911. Where can I find a barrel chambered for this, is there any modifications extractor-wise required? I understand that the slide, magazines, sights and otherwise were stock Colt parts. Any suggestions?
Sirs:Jim Watson said:By my recollections and a search on Webley in USGI here, the .455 magazine is NOT the same as .45 ACP. More important, the .455 magazine WELL is not the same and a .455 magazine will not insert in a .45 receiver.
.455 auto brass is semi rimmed and the mag must be wider. Does this mean that the breechface has to be wider, too?
Best ask DSK and the guys on USGI, but I don't think the barrel is exactly the same, even externally, although I have read that a .45 barrel can be used in conversion, along with a (loose) .45 magazine.
Do you have a supply or source of .455 ammo?
I thought the .455W Colts were WW I guns of 1911 pattern, to supplement the Webley automatics. By WW II we were lend-leasing, selling, and giving GB plain vanilla 1911A1 .45s and S&W M&P .38s
