pete f "Also, the conversion from 45 Colt, or LC, to a .45 ACP revolver
was done to allow only one round for all handguns being deployed. Once
the machine word was done. the revolver would only shoot .45 ACP or
.45 AR."
IWrong on several points
1. The model that the S & W M1917 used by the Doughboys
was the S & W .44 1rst Model Hand Ejector, 1908-1915.
AKA The Triple Lock
See:
http://www.shootingtimes.com/handgun_reviews/smith_12_0507/index1.html
The M1917 did'nt have the ejector shroud, nor the lock on the crane
to make it easier to produce in war time. The M1917s were
originaly made for the .45 ACP and had to use moon clips because another
shortcut was the cylinders weren't counter bored for headspacing
that was accomplished via the moon clips. Now, this confusion may be
because many, along with the Colt New Service M1917 were converted
to the more popular .45 Colt cartridge.
The .45 ACP was designed because the Army wanted a semi-automatic
that would approximate the .45 Colt load in the transition from the Colt
SAA and the failed .38 Long Colt.
2. I never said the .45 Auto RIm was ever issued to our Military.
it was for the guns on the civilian market - in company terms the
M1917 is designated the 2nd model Hand EJector. SOmetime in the
post-WWI era they prettied up the 1917 and it got the ejector shroud
once again and adjustable sights thus the 3rd model
Hand Ejector.
3. THe S&W and perhaps the big COlt had been in production prior to
1917 - it was contracted by the Brits for their similiar round
the .455 Webley ( & and maybe another brit cartridge I am forgetting about ) The .455 Webley was even shorter than the .45r ACP/AR and
it's loading was a heavier bullet that clocked 650 FPS.
I don't know that much about the Braziklian contract guns but I think they
may have been initially made in the USA until the Brazilians got their factory
going - something to look into I spoze.
