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!

    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?!?!?

  • V.I.P.

    It looks funny, but guns are not designed for looks.

  • komrad

    Its not even photoshoped. Its just a 1911 behind a 1903.

  • p.u

    i think if it were a 1911 behind the 1903 the triger guard or slide would be showing out of the top or bottem i might be wrong though

  • p.u

    and to add on top of that last comment the triger guard would be showing because the magazine release is just inside the triger guard on a normal 1911 pistol wich in this photo it seems that the triger guard must have been sawed off because u cant see it so it cant be a 1911 behind a 1903 (replying to komrad)

    Gen. Patton once proposed a 1903 carbine in 45 and had a couple of examples built but the army found it unneeded.
