If you love your M1903 or M1911 don’t read this post
You were warned … This is the Frankenstein’s monster of early 20th Century American arms:
An M103 Springfield in an SBR (Short Barrel Rifle) configuration presumably converted to .45 ACP with a 1911 pistol grip being used as the magazine well.
It is hideous. Something only its mother could love!
Hat Tip: Хроники безумного Макса

Some weird part of me wants that gun, it could only be fun.
According the Springfield Armory Museum website, it was used for testing .45 ACP ammunition. They have another M1903 converted to .45 ACP in their collection, but it is only a barreled action.
Daniel, ah, so thats were that photo is from. I suppose that makes it part of history and not a hacked up job.
No Way!
Gotta be photoshopped!
According to the Springfield Armory Museum, it has been in their collection since July 14, 1941. SPAR 1450 is its catalog number. SPAR = Springfield Armory.
almost looks like the beginnings of an American Delisle carbine (Sp)
what kind of joke is this?!?!?
It looks funny, but guns are not designed for looks.
Its not even photoshoped. Its just a 1911 behind a 1903.
